I took a closer look. Definitely no o-ring, however, there might be a seal around the edge of the reflector. There is plastic ring that looks like it might work as a seal. I did not remove the reflector to get good look at how plastic fits or to see how soft it is. It light gray, nearly white in color. It is conceivable that the bezel presses the glass into this plastic hard enough to form a seal.
That said, it seems the water must have gone into the light by around the edge of the glass, because there is no sign of water below the inside surface of the glass, thank goodness, because that would explain why the light was undamaged.
