i just installed a set or projectors and they work great. my problem is with the halos there are two red wires. how do i know which is positive and which is negative or doesnt it matter. they go into a small black box the puts out 2 red wires and 2 white.

 

ah yes the the 2 red wires. i have the same thing i just tested each side and it was the same both ways. so i figured i was good. it goes 2 whites and 2 reds to the box and then comes out 2 reds. basically like a 194 bulb either way works with the socket. hope this helps. oh and sorry it took so long for me to read this
