Have you tried pushing in at the top and sliding the lens down? I'll have to learn I guess. Also, what bulbs do those take?
On edit: I wonder if those are actually LED. If they are the same as this light, the Chrome actually comes off the top to expose the screw holes for the whole light. They are sealed and not serviceable. Kaper II
Mine has a chrome top and bottom part is lens. No place to squeeze. It is very firm. Must be an easy release if i can find it. It is the light for the outside above utilities. Same as door light.
