K.. so i have a 76 which I've converted all the exterior bulbs over to LED except backup lights. I also have all interior lighting LED except for my turn signal indicators. I've also installed the new LED turn flasher with the ground wire attached. So far brake and turn all work correctly. The headache comes when I turn on my running lights. When running lights are on I don't have drivers side turn or brake in the rear only. All other signals/brake are working. I already replaced the bulb which fixed my random flashing. With original bulbs I have no issues. Any guidance would be greatly appreciated. Could it be a ground issue? Bubba was using wire nuts. I'm pulling my hair out on this!!

thank you

Neither rear Turn signal? ....and Neither brake light?

Do BOTH the turn signal lights work in the FRONT?

The problem is the front side marker that lights w/ running lights and then flashes opposite to the turn signal. That circuit doesn't work with LEDs.

What I ended up doing on mine was changing one wire for the front side marker so it flashes with the turn signal instead of opposite. Downside is it doesn't light with the running lights anymore.

Update: I moved the bulb to the other side rear and doesnt work at all, moved it back and still not working. so I put it in the front which is the same bulb but amber.. bulb not working at all. so maybe a bulb issue.. again.. bad bulb lot?

response to questions..

It was only the drivers rear which had no turn/brake only with running lights on. working otherwise till it didnt anymore.

If it were a side marker wiring issue, then why does the passenger side work flawlessly including with running lights on?
