Where does this taillight ground?

[vegasanthony]

common sense says that a bulb needs a ground and a hot..
Ok where is the ground for the bulb with the red wire?

It grounds through the housing...

Or "it once" grounded through the housing. IF you can salvage that lamp shell, clean it up, then solder a pigtail to the lamp shell, and bolt that to the body somewhere

On the older models, the housing studs make the continuity to the body... Have you tried to mount the housings on the body yet???

Or, replace it with Dorman - Electrical Socket - 2-Wire Turn, Stop with Ground Tab. You can find them in any auto parts store.

Looks like 71-73 dart tail light housings. The ground wire attaches to the trunk lock support on the left side. I will go get a pic of mine.
I would also run a ground straight from each housing to the frame. This will greatly decrease the chance of having a ground issue.
