Take off the grill, I think the indicators need to be unplugged first, then the pop screws along the top of the grill and then pull the bottom. Once the grill is off remove the ring around the headlight (2 or 3 small torx screws I think) and then pull the headlight out and unplug. Reverse procedure to refit as long as the headlights match the plug. It doesn't take long, I take mine out to clean them every now and then.
