My tail lights work The centre light comes on when brakes are pushed Right and left brake lights do not. I've checked the fuse and the bulbs and all seem in good shape. What could I be missing?

Ground at the rear to the brake light bulb ground. Put a good known ground to the case of the brake light bulb holder, and try the brakes.

Also check the wire harness for open circuit (broken wire).
