Is it possible to cut out a window on a regular garage door? I need to

I am not sure what the construction material is, but the outer skins
appear to be somewhat flexible, so I am thinking it is a thin steel
skin with an open cavity inside (or foam).

Any suggestions?

We added several windows to a door that is similar in construction to
yours. I used a cut off wheel on a 4" grinder to do most of the
cutting, and finished off with a sawzall. Drilling 4 holes at the
corners will really help to "keep you honest'.

A real garage door dealer, one that handles commercial doors, will have
purpose-built bubble windows and vent ports designed for a door like
that. The ones I have seen were a 2-piece self-edging setup, round or
rounded on the corners, and had gaskets to keep water from getting into
the insulation layer. As to cutting the hole- careful mapping, and a
couple through-holes for reference points. Jigsaw and a metal blade
(unless you have electric nibblers) to make the holes in the skin, and
fill any voids with stiff foam. You want the edges of the hole to be
solid. Make the holes centered between the hinges, and centered on the
height of the panel, unless you detect an internal rib there or something.
