Hello, I'm looking at adding some LEDs to my boat this spring, and want to swap out the courtesy lights to blue LEDs. My question is, are there led(s) in the existing light that can be removed and a new blue led(s) put in.

If so, how do you get the thing off? Ive pulled the carpet back, and see it is held in by screws, but i can get the chrome piece off the front and I'm afraid ill break it if i try to hard the wrong way. What has everyone else done with those courtesy lights? Is there a replacement that covers the entire hole?
