Has anyone officially 100% found a way yet to run a head light off the white wire yet

[DeathProof]

ive read and read for hours here in the threads and cant get a straight answer its always this will work and that will work followed by no that wont and battery will only work or the light will drain power from your engine blah blah. i got nowhere in these threads on the white wire to light subject. if theres is a way 100% pls share it.

DeathProof,

The Holy Grail of the White Wire.

Here's a link to someone who used the white wire to run LEDs. The system is very limited in the output.

I've been there and done it - just isn't worth it. So have hundreds of other members on this forum and the other forum. The ignition systems are weak already, so why complicate matters? Rechargeable batteries seem like the norm. I am not trying to discourage you, but give you my honest opinion.



Good Luck,

Same here, been there done that and never posted cos it's easier to tuck away the white wire, and use batteries or some innovation of your own to .

i thank you guys thats all i wanted to know without the technical go no where mumbo jumbo i appreciate it so no white wire hook up it is then!

I considered a dynamo hub recently when shopping for a front drum brake hub for my MB. But after reading about peoples' experiences with those, I decided against it, and bought a regular Sturmey-Archer X-FD 70mm front drum brake hub. It would have been nice to reliably generate my own electricity for head- and tail-lights, but those dynamo units apparently make for a lot of complication in the servicing and reliability of the hub. I've already got enough complication to deal with!

The ignition system barely functions as it stands (without drawing current through the white wire); trying to induce a current in the magneto side of the circuit with reduced flux makes things even worse.

Anyone ever try hooking a small e-bike motor to their engine and running power off of that?

Real simple way to answer your question: go to your local home depot or Kmart and get two 300 lumen (12 volt) LED ceiling lights. These generally have an operating voltage down to 6 volts.
Make a housing for the LED lights to attach to your bike (ideally with some level of water proofing) and run the lights in parallel with one set of wires running reverse polarity on one of the LED lights.

This will have each LED light running on one half of the AC sine wave (i guess a 50% duty cycle) from the magneto Alternating Current output.
The same thing works with old style tyre driven, bottle dynamos.

That's a great idea. I didn't realise that LED's (being polarised Light Emitting Diodes) could run off of AC current. When you reverse the poles on one of the LED's the current at any instance would be flowing through the LED with the corresponding wiring for that cycle. That way the excess current always has somewhere to flow. Also the rate of cycles would be fast enough to trick the human eye into thinking that the LED's are always on. Excellent.... now where did I put my white wire!

cool idea.
too bad the op has given up on the hobby.
hopefully someone else can benifit from this.
