Reverse lights aren't comming on
 

Popped both tailights, both bulbs seems to be never even used. Now that I remember back, I don't think they even worked when I bought the car. Any ideas what I should check first?

EDIT: It's a 98 Camaro Z28 A4.

Reverse switch?

What I was thinkin, or told I should say haha. Ill pop it tonight.
