[net.bicycle] Bike Lighting

lkl@houxm.UUCP (L.LUNAS) (09/04/84)

As the days grow shorter I begin to think about the
safe way to continue riding to work. I ride on narrow
suburban roads in southern New Jersey and believe
I need the best lighting system I can find.  I am seeking
suggestions on the "best" system to use in order to see and
be seen. (I would prefer a system I can buy ready to install,
not a kit of parts like capacitors and Radio Shack switches)
The primary objective is to ride safely at a fast speed and
stay alive, aesthetics and weight are secondary.

Net reader's experience with Quartz/Halogen or other of the
newer systems would be appreciated.

Thanks,

I, too have been looking for a safety light.

And one of the best ideas I have seen is a little
strobe light!

It is made by Tekna Lights in Belmont California.

The light is a small slowly (for a strobe) flashing blue
strobe light with a strap.  It is worn on the left arm.

Boy Oh Boy!  You are *VISIBLE* to drivers!

If by "best" you mean "brightest", you want to deal with a company called
Bicycle Lighting Systems in Alexandria or Arlington Virginia. Many issues of
Bicycling magazine carry their ad in the back. BLS is a one-man operation
run by a fanatical EE who works for the government. BLS uses a motorcycle
battery that mounts on the rear rack, running a cable to a 10-watt GE
sealed-beam halogen bulb. It's quite a job to install and keep charged and
balanced, but wow, is it bright!

I outfit my family's bicycles in the following way.

On the front I put a 6-watt Nicad halogen headlight manufactured by Velo-lux
of Davis, California. This is a superior unit, almost as bright as a
motorcycle headlight, that will both light the road for you and make you be
seen for quite a distance. Each light comes with a recharger, and lasts
about an hour and a half between rechargings (just take it inside every
night). You can also hook it up to the Sanyo "kickstand" generator and it
will recharge itself.

On the rear I put a lamp that I make myself, but don't be scared away--it's
really easy. I buy a "Wonder light" (French made) and a high-quality
red rear reflector. I split the reflector open with a chisel, removing the
red front lens from the rear mirror, and glue the lens part of it over the
front of the Wonder light with model airplane glue. I then mount the whole
contraption on the seat post or one of the seat stays if there is no room on
the seat post. The rear light is about 1 watt, but the light shines through
a really top-quality retro-reflector so that it is very visible.

I tow my 1-year-old daughter around in a Burley bike trailer; just for grins
I have installed 4 of these homemade taillights on the trailer. I look like
a flying saucer going down the road pulling baby V. behind me, but the cars
sure do keep their distance.

I can't recommend the Velo-lux light highly enough. It's just incredible. It
costs about $60, and is worth every penny. The Wonder lights are about $6,
and run about 20 hours on one $2 battery.

I would also like to recommend the flashing yellow lights you
can get in various bike shops.  They run for about a year on one
9-volt battery, which is good because the battery is a pain to
replace.  You are extremely noticable with one.  I've also seen
a few bikes around with generator-driven fluorescent tubes that
mount on the frame; they don't make it much easier to see
but again improve your visibility a lot.  It's quite a sight to
see someone riding down the street at night with this wierd
green glow coming from between their legs!

A good addition to whatever other lighting you have is a "leg light" -
a tube holding 2 "C" cells with a bulb on top and a white (or yellow)
lens forward, a red lens backward, and a yellow diamond-shaped lens to 
the side.  They recommend wearing it on your arm, but worn on your leg
just below the knee it bobs up and down as you pedal.  It does nothing
to help you see, but the movement makes it quite visible.

[Of the 10 worst road hazards, >= 5 of them are cars]

While the Wonder Light seems a good idea, I am thoroughly disappointed
with the Wonder 4.5V battery. I've had 2 and both have exhibited the
same behavior - dying even if they aren't used, with maybe a total of 4
hours of service.

I have since been using blinking light - Barron's in Torrance CA
estimates 75 hours between battery changes, and I'm seeing it work out
that way. I'd like to wear it on my leg, but there are several problems:

1. Too easily hidden by cars - even the guy next to you often can't see it.
2. While my leg is coming up, the light is nowhere close to vertical.
3. Even just below the knee, my leg is none-too-small. The strap simply
isn't long enough to go around my leg and stay there while it is flexing.
(The strap has a Veclro closure.)

You can't settle the issue until you've settled how to settle the issue.
