Tail Light Is out
 

I having trouble with my tail light, my right tail light works fine, but my left is out and all fuses and bulbs are good. Any idea what this could be?

Are you sure the bulb is good? Next would be check the contacts of the socket.

Yes, if the bulb isn't blown try rubbing the contact point of the bulb against sidewalk or sandpaper to get off all the stuff that built up on it.

try swapping the bulps from one side to the other Sometimes the bulps are blown and very hard to tell with naked eye

Looks like I've tried every way possible, but now my left tail lights and brake lights are out. Any ideas what this could be
