On my 07 classic the taillights decided to go out on me. First the passenger taillight went out. Then a week later the driver taillight went out while i was waiting for the Taillight circuit board.

I put the new circuit board on and the same thing no different. I have checked fuses and all appear good.

What is the next step or has anyone had this similiar issue on their truck? Should i just start replacing the fuses?

If the fuses arnt blown, there's no need to change them out... Is it just your tail lights? Explain tail lights? Such as just when you hit your brake? Or the whole assembly (blinkers reverse lights, ect.) I would check the wire harness behind the back bumper mounted on the crossmember...

Bulbs do burn out.... :cool:

....Is it a bad wire. It is odd how both went out but went out seperately
Follow the harness back and look for damage....probably at the split for left/right.
