Have a '68 500. With headlights switch on, tail lights work both sides. Brake pedal, hazard lights, right side directional signal does not work on the right side tail light. Right front directional lights up but does not flash. 2 directional green arrow lights on dash....they flash. I use flasher #323 Wagner. It calls for not using Heavy Duty Flasher. Anyone have any ideas? Appreciate it....S
Hi to seaweed, From what you have described it would or could be a bad ground.I would begin with a wiggle test of each ground to see if any have become loose or damaged,then clean and tighten each one.It is also a good idea to inspect each bulb to check for the correct type- filament damage-if they check out,try switching bulbs side for side and see what happens.Often see cheap bulbs cause strange problems.Keep us posted,and we will hope it is something simple. P.D.
