Changing the bulb on the side floodlight

[Explorer777]

Hi, I have a 2011 Rockwood 8317ss and there is a floodlight on both sides of the rig. One is outside the main door up high on the side of the rig. The light quit working and I want to check the bulb. There are 4 star screws around the very outside edge holding the entire assembly to the rig, and then inside there are 4 holes that have been filled with what looks like tub and tile white caulking, (to keep water out????). I'd hate to dig the caulking out only to find out that was not how to take the cover off, but I don't see any other way to get the lens cover off. I'm guessing maybe they covered the screws with white caulking to keep out leaks or keep the screws from rusting??? Has anyone else had to deal with this yet, or know how these come apart?

Thanks.

Yes in the the plastic there are four phillips head screws that need to be removed that gives you complete access to the bulb make sure when you reasemble not to forget to reinstall the black gasket the screws might be behind the sealant so you might have to dig it out any more questions give me a shout back
