To be honest, I do not have a clue why the tailight is out, I'm just trying to help you figure it out from my end of the worldthanks for the tip. i'll ask my mechanic about that when i bring it in.
i'm not trying to sound snarky or anything - i'm just wondering how it would be possible that all three sockets could go out at one time. i can understand if H2O was leaking into the assembly, but that's not happening. i may just have a faulty assembly.
I agree, multimeter is needed to check for powerIf the whole assembly is out, then the problem may not be in the light housing. If you were to put a multimeter in the wires and check for power, that would tell you if the problem is in the housing or in the wiring. There may be a loose connection elsewhere in the circuit.
