The most common problem is switch on side of transmission.(If bulbs and fuse are good) Another common problem with reverse lights is a faulty ground. Check for the black ground wire off the lights in the back. If the connection to the ground (body or frame) is rusted or broken repair it.
The bulb is probably dead or you have a blown fuse or other electrical problem.
