The brake light socket will also burn a hole in the reciever pad on the brake light, mine did. If you or a friend is handy with a soldering iorn, clean the pad and flow solder over the burn hole. Be careful not to overheat the metal pad and melt the plastic light. There are other threads on this remedy. Good luck
