I am trying to install a headlight on my wife's klx140. I already got the wiring on the bike figured out, and the wiring on the switch also. BUT... I bought a chinese headlight that did not come with instructions! I am having a hard time figuring out which wire is positive, which one is ground, and which one is for the high/low beam. Here are some pics: As you can see, the headlight comes with a separate bulb for the high beam and I'm pretty confused. Any help would be GREATLY APPRECIATED! Thanks in advance! Edit: I forgot to mention that although in the first pic there are two green wires, at the end of the cable (where you join the wires with the ones on the bike) there is only one. So there are only 4 wires. White, blue, green, and brown. Thanks!
