Poor earth on lights maybe ???

Hi all, when i got back from the Coombe Abbey get together and parked the car, the rear brake light was glowing dimly and the side light on the same side ( drivers side ) was the same. Would this perhaps point towards a bad earth or connection ?? Took the bulbs out . Only askin as got about 30 mins to look at it before the regional meet tomorrow  8O

That sort of thing always used to happen to me with my Escort.  Usually it was a bad connection on the light board.  I would suggest just taking all the connectors off, giving them a clean and see how that goes.  Failing that on the Escort i just used to replace the whole board.
