No tail / brake lights but have side marker lights?

[stingray72]

OK. so my 72C10 came back from the painter and I've got no tail or brake lights. The side marker lights work though.

Fuse has to be good for any lights back there to work.

Brake switch probably good? when it goes out all lights go out right?

I have LED rears and it's been so long that I've forgotten if there was something else I had to do to get those to work.

Side markers wouldn't work with bad ground right?
