For around town, you can get some dynamo lights, but they aren't powerful
enough for the type of cycling where you had your little incident, except
for perhaps the new Solidlight 1203D.
(cough) bollocks.
But we all know that.
Simply type "Bicycle Lighting" into the Google Search box, then click
"I'm Feeling Lucky." You'll be taken to
SMS's website, which although it contains some useful info is severely
tainted by his refusal to admit that what others use successfully can
possibly work.

I enjoyed his site anyway. I've been reading articles from it for more than
an hour. He seems to have a passion for lights and safety.

As it turns out, the light isn't even that good for being seen. Cars see

I don't know that it matters much what drivers think it is. If they
see it, they'll avoid it - which is the function of a "be seen" light
like the one you bought.
Personally, I think you're barking up the wrong tree. You made a
series of mistakes, and the fault is not with the light manufacturer
or the government. You need to learn from your mistakes, and learn to
take some responsibility.
Your first mistake was, apparently buying the wrong light for your
purpose. That headlight functions well enough for it's intended
purpose: being seen, in locations where street lighting is adequate
for riding at a reasonably slow speed. If you wanted more, you should
have learned what light was appropriate and bought it.
Your second mistake was not realizing what you'd bought when you put
it on your bike and went out for a ride. Why did you not simply
return it, saying "Sell me something brighter"?
Your third mistake was not riding within the limits of your
visibility. Riding 20 mph when you can see only 25 feet ahead is
really foolish.
Your fourth mistake was not being able to handle your bike. A decent
cyclist shouldn't have problems clearing a tiny bit of gravel,
especially on a mountain bike. If necessary, lift the front wheel a
bit on rough parts. The fact that the cyclist in front of you "didn't
notice anything" speaks volumes.
Your fifth mistake was coming here hoping to have everybody give you
hugs and encouragement, and make those bad people stop selling their
product. Sorry, but there's still some room for personal
responsibility in America, and "caveat emptor" still makes sense.

Dear Frank,

By sad coincidence, the Denver Boast featured this article today:

Bicyclist killed in pre-dawn accident
By Mike McPhee
Denver Post Staff Writer
Article Last Updated: 09/24/2007 03:07:57 PM MDT

A bicyclist was struck by a car and killed early this morning on a
frontage road in Adams County.

The Colorado State Patrol said the bicyclist was hit just after 6
a.m., while it was still dark, on the Interstate 76 frontage road
between 88th and 96th avenues in Adams County. Master Trooper Ron
Watkins said the rider did not have lights or reflective gear on his
bike or on his clothing.

He was pronounced dead at the scene, and his identity has not been
released.

He was struck in a traffic lane, not on the shoulder, by a 2004
Chevrolet Malibu driven by Charles Polich, 61, of Aurora.

Watkins said the investigation in continuing but that Polich never saw
the bike before hitting it. Drugs and alcohol are not considered
factors in the accident, Watkins said.

http://www.denverpo­st.com/search/ci_698­5822

The same paper lists sunrise as 6:50 a.m., 6:23 a.m. for civil
twilight.

The map and my memory suggest that the speed limit on the frontage
road would be at least 50 mph, but I could be wrong:

http://maps.google.­com/maps?f=q&hl=en&g­eocode=&q=thornton,c­o&ie=UTF8&ll=39.8645­9,-104.907804&spn=0.­016964,0.02841&z=15&­om=1

It sounds as if the dead bicyclist was riding in the dark in the
traffic lane with no lights and no reflectors at 6 a.m. with his back
to the car that hit him.

Cheers,

Carl Fogel

No, I never have. And I've been riding, and often commuting, at night

No. I'm not trying to raise fear levels. That wouldn't do anything for me.
I'm a cyclist and I'm interested in talking to people who have also seen the
dangers. It don't like to pretend that I'm all fearless and confident. (not
that you do pretend. You may seriously be fearless and confident)

Maybe you're athletic. Maybe that's why you don't get hurt. Have you ever
thought that not everyone has your abilities? Maybe fat, out of shape types
come in here trying to get into cycling. You'd probably want them to cycle
and exercise, but if they do and they get spooked by the dangers, you want

but that is because car driving is pretty
similar no matter what. People ride bikes in a much more varied way.

People drive in different ways, too. They drive on a variety of surfaces
and different cars have their headlights at different heights. Somehow,
the headlight manufacturer's have figured this out and design for it.

Sealed beams were a huge improvement because it gave the headlight
manufacturer control rather than the car maker. Bicycle light
manufacturers have the same control. They should use it.

As a side note, have you noticed that Garrity doesn't make bicycle

There are "seeing" lights and "be seen" lights. The best rule of thumb is
"never outride your lights". Sounds like you either had a "be seen" light
where you needed a "seeing" light, or you were riding 20mph with a 10mph
light.
Again, should it be left up to the individual cyclist to think of when a "be
seen" light or "seeing" light is necessary? Individuals don't have time to
test things extensively. They have to trust merchants and manufacturers.

Interestingly enough, at least two stores (REI and Performance, IIRC)
have been labeling their lights something like "seeing" and "be seen."

Those parties are only interested in making profits. The solution is
regulation.

I agree completely. Let's put a regulation in place that usenet

that thinks otherwise is somehow wrong.

That's why on the web site I examine the pros and cons of each type of

You are correct that the quotes by all those experts and organizations
are their views. I'm not sure where the line should be drawn between
informed opinion and fact. When so many experts, from different
organizations, none with vested interests in selling lights, say the
same thing, it's as close to a fact as you can get.

I have not seen a single organization, or lighting expert, promote low

a little less clear.

They should, IMVAIO, at least state the type of night cycling that the
light is appropriate for. There should be some sort of a standards
association that comes up with a rating system, i.e.

W-Suitable for well-lit roads at speeds up to 10 mph
M-Suitable for unlit roads at speeds up to 15 mph
S-Suitable for unlit roads at speeds up to 25 mph
O-Suitable for unlit off-road trails

You were going down a hill at 20 mph, in an area that apparently had no
street lights, with light that did almost nothing in terms of
illuminating the roads. You had a "be legal" light might be appropriate
for slow riding on well lit streets, where there is no need to
illuminate the road far ahead.

Look at the different types of cycling, and the different cycling
infrastructure when choosing a light.

In Amsterdam, where there is a big infrastructure of bicycle paths,
people use low power dynamo headlights and are just fine with them.

In well lit cities and suburbs where I live, a lot of commuters have
bought the Joe Breeze bicycles with hub dynamos and find them adequate
for most of their ride, and supplement them with a good battery powered
light when they have to go through unlit areas, especially on hills.

The area and speed you described would best be served by a high power
LED, halogen, or HID lighting system.

Cycling isn't for the few that meet your standards. Any of us can legally

that what you want, some minimum level of ability before a cycling license

Supposedly you promote cycling with the time you donate lecturing. How odd

Yes, setting an example is the way to promote cycling. After promoting
cycling in a recent Cub Scout meeting, as a way to reduce expenses, I
was somewhat embarrassed that I had driven to the meeting less than 1/2
mile away (I had a lot of materials to carry with me, but if I had a
trailer I could have carried them). Last night I hopefully set a better
example at a Pack committee meeting, by riding to the meeting at night
with a well lit bicycle (though helmet-less).

Personally, I _love_ night riding. I don't find it hazardous, but it's
because I've taken the necessary steps to reduce the hazards.

Come now, many companies, including CatEye, make lights that are
suitable for different situations. It's not an unreasonable idea that
they indicate which lights are appropriate for which riding situations
(though perhaps they feel there is some liability in doing this).

It's not really reasonable to think that every customer for bicycle
lights is well-versed in all the differences in illumination, beam
pattern, battery life, etc.

Rather than wait for government regulation, the industry should form its
own standards.

Reflector and lens design as well as bulb type are what make a light
good or not. I was thinking about bare bulbs. When I lived in the US I
got Euro-spec lights (reflectors, lenses, as well as high wattage
bulbs) on (almost) all my cars. The focus is much tighter and the
projection much further. They are more of an irritant to other drivers
if they are out of alignment, but I'm the sort of guy who is careful
about that sort of thing. On a recent trip to California I recall the
lights on my borrowed US-spec 2007 BMW X3 as much worse than my cheap
'98 Euro-spec Fiat.
A modern US spec car (say a 2002 Jetta) does not use sealed beam
lights. The lenses and reflectors are designed to meet US DOT
regulations. If you take a trip to a Pep-Boys there are all manner of
bulbs available to put in. Some are for sure crap, other not so.

similar no matter what. People ride bikes in a much more varied way.
People drive in different ways, too. They drive on a variety of surfaces
and different cars have their headlights at different heights. Somehow,
the headlight manufacturer's have figured this out and design for it.
Cars operate in a very well defined and known speed range. Most cars
drive from 0-30mph in town, 40-50 when things are a bit more open, and
60-80 on the highway. There aren't many cars that don't get used in
all those ranges. Bikes are different. Some never see speeds higher
than 8mph! The needs of cyclists are much more varied IMO.
Sealed beams were a huge improvement because it gave the headlight
manufacturer control rather than the car maker. Bicycle light
manufacturers have the same control. They should use it.
Sealed beam just eliminated rust on the reflector.
As a side note, have you noticed that Garrity doesn't make bicycle

I don't know. Because it is a difficult product to do well and they
don't want to make crap?
Joseph
When it comes to safety features, I prefer that manufacturers assume that
the bicycle is going to be used in the most demanding conditions so that all
bikes are equipped with quality lighting whether they're going to be used at
night or not. Can you imagine cars being sold with no lights because the
owner thought he wasn't going to use it at night? The one cheapskate's
attempt at saving a few dollars can affect the safety of everyone on the
road.

For some unknown reason, being a cheapskate and scrimping on equipment is
tolerated among many of the cyclists here. It's no wonder the law doesn't
see you as reasonable, law abiding citizens when you have an accident. They
happily put the blame for accidents on the individual cyclist here in
America.

Sealed beams are not all that common any more on new cars. Most
headlights now use replaceable bulbs, and you can buy bulbs of various
quality.

You're correct that the DOT specs are often crap. One of the biggest
annoyances is how they've failed to regulate daytime running lights,
even though they are well aware of the problems. Some vehicle
manufacturers use the high beam bulbs at reduced brightness as the DRLs.
It's very annoying to other drivers, and the DOT knows it. But they are
controlled by the vehicle manufacturers and hence do nothing.

It doesn't matter whether you like or dislike the DOT standards, they
exist and have existed since 1940. Prior to 1940, manufacturer's
operated pretty much like the bicycle light manufacturer's do now.
Caveat Emptor and if you crashed, well it must have been operator error.

Now, we have people saying here, "Well, you should have known that the
light was crap." Why? If someone sells a safety device, like a fire
extinguisher, or a poison gas detector, or a GFCI receptacle, car
headlight, or a circuit breaker, or a fuse, or just about anything else
you can think of that has to do with safety, it has to meet some sort of
minimum standard, that being it is fit for a particular purpose.

But, if someone spends $30 on a light, they are suddenly supposed to
become an expert at optics? And miraculously "know" that the light isn't
fit for a particular purpose? Do you know what the UL standards are for
half the things you use that are UL listed? Why not?

I'm not an expert at headlights, but I don't have to be. I buy a
replacement when one burns out, and even if I buy the cheapest one the
discount auto store has, I know that it won't be so dim I can't see.

Over here we've got standards for bike lights. SMS won't like them, but
that's his problem.

However it's not too difficult to do riding which requires more light than
the ones meeting the standards give - eg off-road. If somebody is riding
such that their light isn't good enough, it's their responsibility, not the
light manufacturer's.

Even DOT headlights may not
provide optimum lighting in many conditions.
Aren't DOT headlights in fact notoriously weak? Or have the rules caught
up since the 80s?
The rules are flawed. In some cases they're allowing headlights which are
far too bright, because they're using watts as the unit, which is
ridiculous with HID.

Somewhat off topic but, I was out tonight using my headlight on a rough rail
trail. Suddenly a light was coming towards me. Another cyclist on the trail
and I think he was using the same light as me. We didn't stop and compare
though. So far I've never seen one of those expensive, high powered lights
in use. This is the first guy I've run into with a headlight. Most people

Come now, many companies, including CatEye, make lights that are

they indicate which lights are appropriate for which riding situations
(though perhaps they feel there is some liability in doing this).
It's not really reasonable to think that every customer for bicycle
lights is well-versed in all the differences in illumination, beam
pattern, battery life, etc.
Rather than wait for government regulation, the industry should form its
own standards.
It's really reasonable to think that a person riding a bicycle at

Idiot! Do road conditions go from smooth to inch diameter gravel with no
warning, no sign? Only for bicycles on shoulders. Nobody would have been
ready for that. You're not going to go down a hill at 6 mph for 50 miles
just in case there's some gravel every 50 miles.

I suggest you read about their experience, both in cycling and with
lighting systems. I can't vouch for the depth of their technical

in practice.
Except they have not used the new Trinewt, which is the lightweight,
intensely bright LED system I would like to know about. They have not
used HID from what I can tell.
No, and neither have I. But if your qualification for "expert" means
trying each new model of bike light whenever it hits the market, it
sounds like you're demanding some very well-funded "experts"!
Without getting into any issues you may have with SMS, are you telling
me that the non-SON, one-third price units are as good? Could I get
lots of light for $150?
Yes, certainly. You'll go from undetectable drag to barely detectable
drag, but the electrical characteristics are almost exactly the same.
But of course, whether you'll be satisfied with my definition of "lots
of light" is another matter.
I don't demand - and in fact, dislike - having 40% of my lumens wasted
by going up into trees, even though some people include those lumens
in their "lots of light." Likewise, I find that I don't do well
aiming an unfocused light low, with an overly-bright spot just in
front of the bike, so the stray lumens don't go as high. It's bad for
my night vision.
What seems to work best is a well-aimed beam that's nicely cut off
above road level, so to speak, so a lesser amount is wasted up into
trees and road signs. It's best if the brightest part of the beam is
just below that cutoff, so it shines further down the road. It's best
if the part that shines closer to the bike is a bit dimmer, so night
vision isn't washed out.
With that scheme, I get "lots of light" - i.e. better than most bike
headlamps, and plenty for my riding - with a Soubitez roller generator
that's over 20 years old. The lamp I use with it (or its twin) is
available for about $20. I normally use a battery powered taillight.
I sometimes use a 3 Watt bulb instead of a 2.4 Watt, but I don't
really see much difference, unless it's in the longevity.
If you are telling me I can get lots of light
with a $150 investment, then I will build that wheel and resurrect one
of my old beater bikes to put it on.
It sounds to me like you should try a high-end Shimano hub unit - but
replace its headlamp with, say, a Lumotec (see
But for less trouble, perhaps try a good bottle generator first.
They're noisier, but they'll allow you to roughly evaluate what the
lights are like.
If you are telling me I don't
need "that much" light, then we will just go round and round because I
need as much light as I can get with my poor night vision and frequent
riding in the rain (but not tonight because it is beautiful).
Well, I don't know your night vision, so I can't say. You're in
Portland, aren't you? If I were you, I'd get myself over to Citybikes
on Ankeny, and talk to them. Maybe they, or someone they know, can
arrange to let you try a bike with a decent generator set.
You may not like it. Some people really do have terrible night
vision. And really, it does take more mechanical and electrical skill
to install a generator (although that's a once-only operation). But I
guarantee, if you're satisfied with the light output, you'll love the
convenience. For me, it makes my bike a much more practical vehicle.

When you buy a motor vehicle, decent headlights are part of the deal.
The driver's ed course referred to stuff on outrunning your headlights
was more in reference to rain, fog, and snow, than driving in clear
weather, at or under the speed limit.

With bicycle lights, when you buy them there is very little indication
as to their adequacy for different riding situations. It would be a good
move on the part of the lighting manufacturers to come up with some kind
of a system that indicated what type of bicycling the lights are
adequate for.

You're new here, huh?

Once all bikes use lights, the economies of scale come into play. The $400
lights can come down to $100 or less. If that's too much money for the kid's
bike, maybe the kid shouldn't have a bike. What kind of jerk sends their
kids out to play on darkened streets on a bike with no lights? Look in their
garages and you'll probably find a $6000 ATV and a snowmobile. They've got
the money. They just don't see the value and they look at bikes as a toy.

Actually, what needs to happen to drive the costs down is for the
bicycles to be sold with adequate lights from the factory. An
after-market accessory that costs $200 at a bicycle store probably costs
about $10 when included on the bicycle as part of the manufacturing
process. Even a 3W dynamo and a decent LED light would not raise the
manufacturing cost by more than $10 once the economies of scale kicked
in. Attending the Taipei International Cycle Show and Interbike gives
you a new appreciation for just how inexpensive many high margin
accessories actually cost. But as long as their is no legislation
requiring adequate lights, it's much cheaper to stick a "Do Not Ride at
Night" sticker on the frame. Not that I favor such legislation.

You have to laugh when you see the dire predictions regarding the amount
by which various automobile safety and emissions equipment were going to
increase the price of vehicles. Once economies of scale kicked in, the
cost of stuff like seat belts, airbags, catalytic converters, safety
glass, anti-lock brakes etc., plummeted, and new car prices, adjusted
for inflation have also fallen.

OTOH, since most people have no intention of riding their bicycle at
night, it's unfair to burden them with even that extra $10. OTOH,
without decent lights included, they'll probably never even be willing
to ride at night, which requires the effort of buying and installing
lights. OTOH, some types of bicycles would rarely be used at night even
by riders that do ride a different type of bicycle at night.

Why would they?
If you asked a manufacturer which light you need, they would say that
THEIR light is exactly the one you need.

Do you think they would say their light is no good and you should buy
the oppositions?

For us, it's important to be able to offer a few dozen products at

Have you come up with that safety device that is made with no standards

In the case of the light I bought, that would be zero MPH since it
didn't light up anything. And it was zero. I walked my bike until I got
under a street lamp and could see, then rode a bit and walked some more.

When I got home, I took it off and shined it around a room. The walls
showed up perfectly, but the beam was so diffused, it didn't do anything
for the floor. So even if I had tried it out at the LBS I bought it at,
I wouldn't have known any better.

Why is it a law that bikes must have reflectors when sold and especially

You know why. The bike manufacturer's control the governmental agency
that requires them to be there.
And besides, if you did (say) install a permanent headlight on every
bike, it would stop working in very short order. Batteries die even
when not used. Contacts corrode.

C'mon. now you are getting stupid. Headlights burn out. Does this mean

You make it sound like everything is impossible and or ridiculous. Car
manufacturers have made cars that ship with working lights. They stay
working for the life of the car. Of course batteries wear out and bikes
don't have generators, but you also forget that batteries last for years
these days. If they're not used, they have a shelf life of 3 years. If
they are used, cyclists will buy more. LED lights last hundreds of hours.
Rechargeable lights can be recharged in fifteen minutes and also last many
hours.
Once all bikes use lights, the economies of scale come into play. The $400

Check out the rules in Germany. All utility-type bikes (don't know the exact
rules - they do manage to exclude MTBs and racing bikes) must be fitted with
lights, and they must be of a certain standard - and possibly need to be
dynamos too. But that's a country where the bike isn't seen as a toy.

OTOH the lamp you were using possibly meets the standards in place.

"_Getting_?" That threshold was passed years ago.

What makes sense is a hub dynamo and good LED headlight. If included at
the point of manufacture they'd add only a few dollars to the price of
the bike. What makes hub dynamos and good dynamo-compatible LED lights
so costly is that they're a low-volume specialty item.

Look at the Joule hub used by Dahon.
"http://www.speedma­trixdepot.com/catalo­g/index.php?main_pag­e=product_info&cPath­=2&products_id=46".
A $30 retail price for the hub _and_ a Hella FF Micro Halogen
lightlight. This means that it has a manufacturing cost of somewhere
around $5-7.

A few manufacturers are starting to include a hub dynamo in some bicycles.

No. The Cateye EL300 is far from what's required in Germany. With fresh
batteries the EL300 reaches a maximum brightness of 4 lux in 10m distance
- quickly dropping to 2 lux. Minimum brightness requirement in germany is
10 lux. Cateye sold a special version - the EL300G with an efficient
switching regulator instead of the simple resistor inside the EL300 - but
still it is not allowed to be sold anymore.

If someone decides to use a EL300 as his only light, he has to go
appropate slow (not much more than walking speed). The EL300G is a nice
torch at home...

Thats wrong. More than 50% of the bikes sold in germany come with a hub
generator today. An increasing part also comes with a LED headlight
already. Bike manufacturers buy hub dynamos for less than 10 Euro and LED
headlamps (like the Basta Pilot Steady) for about the same. Such bikes (7
speed hub gears, fenders, lights, usable brakes) come at around 200 Euro
here.
