I was not clear. The bulb cover does twist off to allow changing the light bulb. However, I was referring to reaching the internals under the bulb. It appears the flat back that the magnet attaches to snaps in place, and I cannot get it open, yet.The bulb area can absolutely be opened - can't recall if the lens just twists off or if it's glued; pretty sure it twists off as I replaced the bulb in one of mine with an LED and put the lens back on - don't recall having to do any special tricks to make it happen.
