Has anyone repaired the Led Tri Light Bar on there bikes, mine is not working, I tested and there is power going right to the circuit board....thanks

 

I don't know, pull the light out and see if the wire is loose on it? (LED's should be a very simple circuit card.) (Does that work as a brake light too? I never noticed) If it is just a running light, it would be very simple to trouble shoot. With an ohm meter probably, also a voltage meter after it's out, plug it back into the bike and check voltages on the card? It should be simple enough to follow the path visually I bet.
