The Stovebolt Site Forums The Shop Area Paint and Body Shop Question re: 3 lights on back of Suburban and Panel

Is the light on the left barn door the actual BRAKE light, and the ones on the rear quarters only lit when the headlights are on?

I have to rewire them all, and am trying to figure out the best way to do them.

EDIT: apologies, I meant to put this question in Panels and Burbs

I believe it is a dual contact bulb socket.
If it's socket is a two contact bulb socket, it's a tail/license and stop. If single contact bulb socket, it's a tail/license light.
1. For dual contact socket: The less bright filament is just spliced into tail lights. The bright filament must have a separate wire from brake switch. (you don't have to use it has a brake light even though it has a dual socket).
2. For single contact, splice to tail lights
