Just got some new turn signals for the back of the bike and they are LED. I am leaving the front alone so I shouldn't need a load equilizer but I have a question on if anyone has wired these up before.

On the new turn signals there is a red, yellow, black and blue wire. Anyone done this before and what wire went to what color wire on bike?? Any help appreciated.

Thanks

 

Doesn't quite make sense to me! Are these universal lights, or Harley-specific? Four wires seems to be too many IMHO, as it suggests they have three functions, whereas our bikes normally have only one (as turn signals) or sometimes two (turns plus brake). Black is probably ground, red is probably turn, after that....

Hopefully someone else will have something to add!

 

What does the instructions say?

I'd guess one is constant power for running (opt)
One for flashing.
One for ground .
One for brake. (Opt)

I got them off ebay. They are nice heavy lights. Aluminum body and led bulbs. I got a 9 volt battery last nite and played with one.
The black wire is ground.
The yellow wire is running lights (it is dimmer than the other 2 when attached to battery)
The other two wires are the same brightness so I guess one can be brake and one can be turn signal.

Since I have a brake light I think I will just not use one of the wires and just have running and turn signals.
