If you go to the Martin garage door website and search around you will find countless window shapes. You can also locate a dealer near you. Shouldn't be any problem but I have a feeling it won't be cheap.

The moulding should come off, screws, clips,???. We always replaced with plexiglass, that way you only replace each pane once.

If you live in a cold climate, insulated doors make a big difference in winter and summer. I replaced an old sheet metal door with a double steel wall insulated one and it's the best money I ever spent. If you do replace all 3 please try to make sure they don't get scrapped. Donate them to the Habitat for Humanity Restore or a similar place.

Thanks, My3dogs. As I recall, the decals or paint or whatever makes the design is on the inside of the glass, somehow. Not the inside of the garage, but actually inside the window--maybe between two panes of glass? Oddly enough, my mom just bought a house around the corner that has the same weird thing on an exterior door. Even though it looks like a single pane of glass, there is a dragon (!) somehow in the glass although you cannot feel it or find anything to scrape or peel off on either side. Before she bought the house I saw the dragon and thought "oh, some kid put a decal on this window, I'll peel that off for mom before she moves in". Then I set about trying to do it and ???? cannot even figure out how it is in there!
