Replace brake light on 2015 Itasca Suncruiser

[arneinfloria]

The lens on the top right brake light on my 2015 38Q is broken. I have purchased a replacement assembly, but I am not sure how to install it.

The only screw I see is an Allen screw on the right side. I am reluctant to unscrew it as I have no idea what it is connected to, or if something behind the surface will fall down or out. Any suggestions.?

PS I will be selling my rig as soon as this problem is fixed. Check it out at www.thesen.org

If your rig is anything like mine, stick your head under the back and look up between the rear cap and back wall. There is lots of space to see how the light is attached.
Hope that helps.
Happy Glamping.
