Hi everyone. Some times my brake lights work, sometimes they don't. Like now, the passenger side isn't working but the driver side is. I'm fairly confident that if I wiggle the sockets, they will work for a while. I tried to clean the contact points of where the socket meets the body, but this still occurs. Is there a product or substance that can be used to promote a good contact?? Guess this would be a socket grounding issue. Many thanks, Carmine.
