tail lights

Hey guys been a while since I've posted, Rivi has been running great but Ive run into an issue with the tail lights. All my lights seem to work great (brakes blinkers) but my parking lights work one minute and don't the next. At first i was blowing the taillight fuse constantly so i tried to troubleshoot and inspected the sockets and ended up replacing a couple of them. The fuse hasn't blown for a while but still am having issues. I was thinking maybe the next step is replace the switch?? What do you guys think?

Exactly the same symptoms I experienced....only on my 65 when the parking(running) lights weren't working, neither were the instrument lights. A new headlight switch solved the problem initially but it started acting up again soon afterward.. Apparently new switches are notoriously defective, but relatively inexpensive, so I tried again. The second new switch performed properly for a year or so(20-30 uses) before returning to the same symptoms. Now I suspect another faulty switch or an improper ground somewhere in the circuit. Until I sort it out I'll limit my cruising to daylight hours, which is OK....I do a full-body cringe every time I deploy those 50 yr old clams. Good luck!

ya I think I have the same issue with my interior lights..thanks for the info I guess I will pick up a switch..I feel your pain about driving at night I have to plan my trips around making sure I'm home by dark haha
