12 volt front light flasher

trying to keep motorists "seeing' me as much as possible
I was thinking of wiring a flasher relay to my light and activating it with a horn button
I would just need this augment at intersections

one of my colleagues got pretty banged up last week when a car turned into him
while he was going thru the intersection


anyone else done this?

I already have a 12V system, which is simple and cheap to put together. Since I have a rear flasher already hooked up, I might invest in another one for the front, maybe $10; a switch, $5.

This site describes how to build a high performance, rechargeable. lighting system without spending a lot of money. You can spend as little as $40 to construct a system, complete with a sealed beam headlamp, xenon strobe tail light, rechargeable battery, and charger.

Thanks. There are currently two 12V flasher circuits posted there; the second (more recent) one is a bit simpler.

I use it for flashing 3-4W worth of LEDs, which can turn on and off quickly; if you use it for incandescents, you may want to slow the flashing down a bit (say, by increasing C1). I don't know if constant flashing will shorten bulb life, though.

If your lights pull enough, you may be able to just use an automotive (or motorcycle) flasher module, available for a few bucks from your local auto parts store. They come in "thermal" and "electrical"(?) flavors, with the electrical one supposedly being more efficient and reliable. I tried a few, but none would make my LEDs flash since the power draw was too low.

And don't forget this thread for horn, battery hook up and other goodies. Nobody's posted a LED cattle prod there yet...but give 'em time.

Total Geekiness

just an update

I tried my flashing lights this morning, using a standard 552 flasher, seems to works well
control is with a push on off button,

I used it on this morning commute, going thru several intersections controlled and uncontrolled

I GOT the motorists attention with it for sure
