If it's this style, you just squeeze the lens on the top and bottom and it pops right out. There should be two small tabs on top and one on the bottom. Or, just press down on the top of the lens and it'll pivot out on the lower tab.

Yes, I'm going to switch to LED but had some leftover led bulbs from replacing the bullet lights so going to try one of those first. If they're not bright enough I'm going to get the one you used. Thanks!
