Old headlight switch started to get warm so I replaced that. Went for a drive last night. After 45 minutes with the low beams on the lights went out and then came back on at fast intervals. Both the right and the left went out together. The running lights and tail lights were unaffected. Turning off the lights for a bit allowed them to work againfor a moment or two. Using the high beams made it happen almost instantly. Did I get a switch wit ha bad breaker in it or is there something else going on? Where is the most common place to start looking for a short or something on these? Could the sockets go bad and cause this?
