If you want to change the rear bulbs on the g35 coupe, you'll need to unscrew 3 bolts in the back of the car. Go into the trunk, pull out the fasteners, find the three bolts that stick out, one with a white cap and one is recessed a little. I think 8mm deep socket will help with the recessed one. Unscrew them and pull assembly out the rear of car. Then change lights. For pics check out
