Removing the rear bumper is a pain, too! It's not necessary. There are a lot of small bolts you can't see! The inboard lights are pretty easy to get at thru the license plate hole. You might have to remove the back-up lights if your arms aren't slender. The outboard lights can then be reached thru the holes for the inboard lights. Use a 10 mm socket on a 1/4" drive ratchet.If you're still having problems, the right hand outboard light can be reached easily by removing the right rear inner fender shield, which is simple to do compared to removing the bumper cover! Unfortunately, the antenna motor is in the way on the left side, so this doesn't help on the left side.For re-assembly, install the outboard lights first!
