Check your grounds on that harness, the lights I assume are dim?

is that with the bulb plugged in still? with the ignition on?

Forum favorites: When darkmanX beat me in a roll, the cover page red Redline is right-hand drive, the GMPONE crew and all the other members I met, the few twincharged RL's out there, and of course my original purchases from Ron9919 which gave me my first mod bug.

I has to be a ground issue, trace the the harness back from the lights towards the junction block. Make sure the ring terminals are not green and are making solid contact with bare steel.
