SMB West installed a penthouse on my E350 RB in 2017. Two weeks ago I noticed the rear brake light not really secured anymore. Wiring was good and it was still mostly sitting in the proper hole, but it surely wasn't going to be weather or dust proof as I was ready to head out on a trip to the mountains with afternoon showers in the forecast in a few days. At this point the wiring was the only think keeping the light with the van.
A quick examination with the penthouse down didn't tell me much as the wire was too short to get a look at the back of the housing to see if a tab, bracket or backing plate was missing. There was a foam gasket on the outer flange but no evidence that it had previously been stuck to the van with any adhesive. Looked to me like it was designed to be compressed and create a seal by something from inside the van.
When I got to my campsite and raised the penthouse I was relived to see the light and wire were accessible outside the canvas. But again the short wire didn't allow great access. I was able to contort myself and snap a few pics with my cell phone but still don't see any clues other than the lack of anything to indicate it might have been held on from the back.
Currently being held in place with duct tape inside and outside.
Does anybody have any experience/knowledge of how they are suppose to be secured to the penthouse?
Or can someone try to take a look at theirs to see if they can tell how it is attached?
Here are my pics:
