2006 W900 lights are haunted. Help!!!

[Rawze]

I remember a time or 2 in the past on those Pete's where wonky brake light bulbs would let power go somewhere it should not go and bleed thru the ground circuit somehow.. but one of the opposite bulbs would glow dim with the truck lights switched off.

Not likely your particular issue.. but one never knows. Just making note that i have seen this, for those following this thread.
