led brake lights from ebay..how do i wire these?
 

Hello all, I bought these little led brake lights on ebay. all there is , is 2 brown wires on them. I had the taillight on but not brake,can anyone tell me how to wire these so brake and taillight work? thanks a lot if so, chris

well first you need to figure out which one is the positive and which one is the negative. Are you trying to wire them up as both brake and running lights? If so there is a bit of wiring and soldering that will need to be done. As long as you're willing to put the effort in I don't see how we can't get it to work! First what bike do you have? To determine which wire is the positive and negative you can either use a 9v battery and touch the wires to either end and see if it lights up or you will need a multimeter. Set the multimeter to the diode/continuity setting. Usually,the multimeter will supply enough current into the LED which will just barely light it up. The black (common) lead on the multimeter indicates the negative (cathode) lead, and the red indicates the positive or anode side.

thanks , its an 09 600 rr. ill get to it in am.
 

Hi ,thank you for the reply. yes I need as both brake and tail lights. there are 2 lights . I wondered if the intention was one light for each function.? ill let you know more whrn I get up. thank you again, it helps a lot

If there`s just two wires then you have to wire them so that one is the running, and the other the brake light. If the wires are the same color and there`s no stripe, notch or anything on one of them to differ them from the other, it is possible that it can be wired either way, some modern LED lights have in-built electronics so they can be connected both ways. But I`d experiment first before soldering them in, wasn`t there a wiring instruction in the box? If they came in a blister-pack the instruction is often printed inside the cartboard card.
