Seriously, is there no way to get to the rear of the headlights from either up top or underneath round the front forks area? The latter might require one to get down on the ground, and look up to the underside of the front in by the forks. Insert a hand up there and do some exploring... might find the rear of the headlight using such a method. It's worked for me in the past.
I'd find it unbelievable that there isn't some other method to get to the headlights to swap out a bulb on the fly without removing the tupperware!
