Changing the light bulbs is a challenge.

I too sliced my finger tip on the glass and gave up. However, I found a solution in my bathroom. The small locking suction cups that attach to our shower tile have a powerful seal when affixed.

Be sure to clean the bulb/glass of any grease, center the suction cup, press in place, and lock it. Then twist the bulb a quarter turn to the left. The bulb should come out with a gentle tug (or two).
