Car: 53 Belair - stock - converted to 12V long ago I am trying to chase down an intermittent brake light failure. Switch is good, grounds are good, bulbs and sockets are good. Apparently, everything on this car runs through the headlight switch. This car was converted to 12V prior to my ownership. Can the OE headlight switch handle 12 volt? (orig. 6 volt). My dash lights are intermittant as well. I don't want to start chasing down a switch if it's repairable or not the problem.
