How do you get an explosion that flashes light with no oxygen? The kinetic energy of the incoming meteoroid has to go someplace. Some of it's going to go into the ejecta, much of it's going to go into a sound wave that propagates through the moon, but some of it's going to go into heat. The heat is enough briefly to ionize some of the material. As the ionized atoms recombine with electrons, they give off light.
The hot matter that is left over will also, for a time, give off light through incandescence, just like a light bulb filament. Hot things just radiate light.
