RV Luminaire VR bulb change

[nhinze]

I'm trying to get to the bulb of one of my RV Luminaire VR ceiling lights. I got it out of the ceiling and was able to pop it out of the frame. However, I still can't get to the bulb. See attached picture. What's the next step? I can see any screws.

The trailer is a 2006 Jamco Horse Trailer with LQs.

In the fist picture, at the bottom of the lower piece I see what might be a pry spot. Perhaps just enough for a 1/4" flat screwdriver.

I know light fixtures, but nothing about horse trailers...
