Just bought a 79. My question is, is it the inner or outer rear light that is the turn signal, right now when i use my signals the left one activates the outer light. The right one activates the inner. Im sure its just an incorrect bulb placement, but not sure which one is wrong.
thanks for any help. I'm sure I'll have more questions. I never leave well enough alone.

Inner rears are back up lights unless a previous owner did a bubble light conversion. Sounds like the lamp holders on the right side may have been swapped.

All four lenses are fully red.

As mentioned, the only 4-red-tail lamp C3 model was the 1968 which also had back-up lamps installed in the lower rear panel. Many later-C3 owners chose to convert their rides to 4-red-tail lamps...but many didn't do a good job of wiring.

The OUTER lamps were the turn signals; the inner lamps were tail lamps and back-up lamps.

Sound like an aftermarket bubble light conversion. Something like this?

In 1979 the inners house backup lights only. The red around the white center is a reflector.

The outers are the brake/turn/tail lights.

Sounds like the bulb holders are in the wrong lenses on one side.

doesn't have to be an aftermarket conversion, could be just 4 brake light lenses and new sockets for the inners, and wrong bulbs or wiring done wrong or lost grounding etc.

Outside sockets have 3 wires.
Left side:
Brown = tail
Yellow = Directionals & Stop
Black - Ground

Right side;
Brown = tail
Dark Green = directional & Stop
Black - Ground

Inside sockets have 2 wires and were for back up only
Brown = back up 12 volts
Black = Ground

I put the bubble light kit on my 81.
Iiked them on my old 68.
Cut and soldier the wires and put back up
