On my 69 911 E that is nearly completion of a total restoration I have a bit of an odd blinker situation that I am trying to understand. All four parking lights work. All turn signals work except the right front that does not light up at all and the left rear blinks rapidly. All four flashers work as they should except the right front which again does not light up. The bulbs on the right front are good and it previously did function as it should. Has me a bit puzzled since the right front running lights work which suggest it is not a socket contact issue. Any suggestions would be much appreciated.
