Last March when the headlight switch decided to short out and eliminate the tail lights on my '67 coupe I went to the emergency flashers for a back up ---- well guess what the emergency flashers after prolonged use burned up the turn signal switch thru which the brake lights run. So long story short - the minute the head light switch starts getting fussy get rid of it or fix it somehow because if u are stuck out in the middle of nowhere with no running lights the flashers will eat up your wallet in a hurry.
