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
