Hi folks...

on my 65 c10 stepside, 8 ft bed...
I replaced the bulbs on the tag lights, and they were working fine.
Then a few days ago I noticed that the drivers side blinkers didn't want to blink with the engine off, with the nightime lights on. It would blink slowly, with the engine on and the nighttime lights on Hmn.
Then, last night one of the tail light bulbs wasn't working... and tonight I was buzzing around, I flicked on the driver's side blinker, and it blinked jsut fine... well, I stopped, left the engine on, and both tag light are out. I haven't pulled them yet to check if they are blown or not, but I just replaced them both not two weeks ago... very weird.

Also, anyone know the modern part numbers on the correct bulbs to use in the tag lights?

Any ideas on things to troubleshoot?

Thanks.
