Positive wire on tail light bulbs?

[KrunkyTB]

Ok, i bought a intergrated taillight, installed and my brake light was always on, I adjusted the switch and now my tail light wont work at all, so, i broke off some wires when that are connected to the bulb end and need to re solder new ones on a new bulb end, is it the brown solid wire is positive or the black /white stripe?

I dont have anything other than the owners manual and I cant find a diagram. I just did a mod to mine and cant remember which is which. Do you use a test light?

The brown wire is positive and black/white stripe wire is ground.

thanks for info, i think one is actually for break light, other is black running wire and other is ground, makes sense, if not when i solder it i can always unwire nut them and switch em, thanks for info, will post how it went cause the integrated taillights i bought seem to be junk from alternative solutions i think is manu.

White with black is for the brake light, but you can check out this thread: https://www.hayabusa.org/forum/general-bike-related-topics/62018-tail-light-brake-light-turn-signal-wiring.html
