Palms,
If that is the oval shaped light above the entry door then the cover pops out, held by a tiny rim around the edge. Push up from the bottom edge and flex the cover just enough to release the rim. I usually use a small screwdriver working carefully not to break the lens.
I replaced the standard automotive lamp with one that has 36 leds on it. It’s brighter than the original but not bright enough so I’ll be adding a 15’ led strip below the awning wired to that light.
Having said all that, if you have a different light I’m probably not going to be much help. My previous fivers had round scare lights on both sides but I don’t recall changing bulbs.
