Reread the the posts I answered your question on motorcycle lights which was an answer directed to you but I didn't put your name in the post. You did ask about the spec. on the bulb well thats a trade secret to find out you will have to buy a light or dig real deep as I posted my finding on the bulb to use and how to make the light before I was ever on this forum
My sayings about blowing smoke is not pointed at you but is at Mr.Harp and his remark about using the white wire to power up lights making the mag go bad. I don't know what type or size of lights he or the people that's had the problem been using but I can tell you I've yet to replace a mag/coil /cdi on a bike using the lighting system I came up with powered by the white wire. I build the light housing out of fiber glass and use off the shelf items to make the rest of the light so its not rocket science. Biggest problem is getting the right bulb combo that will work and be bright enough and not kill the engine or burn out the bulb. So I hope this will clear up any misunderstandings.
