i bought a headlight from custom chrome. problem is, it has 5 wires. blue, black, green, white and brown. any ideas what goes where? my last headlight only had a yellow and white( high, low and it was self grounded.)

 

How many light bulbs are there? You shouldn't need more than 3 wires for hi/low beam circuits. If you don't have the instruction sheet, you might have to trace the wire one by one then.

 

didnt come with instructions. im assuming theres only one bulb.

 

turns out the black and brown wires power a very small bulb. and the white, green and blue do the hi/low. no matter which one is the ground, the other two work as hi/lo is this normal. id assume the green is the true ground?

 

I ran into the same thing I put a drag specialties lamp on a springer that was in the shop for a collision repair. Since it is a dealership, it has to be done right and look oem, even though it is aftermarket. I removed the wire harness from the old headlamp. The hole in the new headlamp was too small, so I drilled it out and installed the harness in the new lamp shell. I plugged the bulb in and all was good. No soldering, no splicing an oem look.
