Saab: Rear Running light doesnt work, Failed rear lights

Question
Hi, my rear right running light just stopped working. I changed all the bulbs, checked all the fuses and nothing. Please help!

Answer
Chante:
Since you did not specify the make and model of your car, I can only offer general suggestions.

 The most likely cause of your probelem is a bad ground connection somewhere. That condition commonly occurs in the running light assembly. WD-40 or equivalent, applied to the bulb sockets and surrounding areas can help restore good connections.

 If grounds are all ok, then I would consider running a separate wire directly from the fuse to the light bulb socket...often much easier that trying to find the actual fault, somewhere "deep in the bowels" of the chassis!
                   Hope this helps,
