I have had mine exposed since February with aftermarket LEDs and no issues! It has been through A LOT of snow and rain and rocks since then. Doesn't look worn or anything. I think it is pretty shielded in there.I removed mine this weekend. I live in Florida and definitely was concerned with elements getting to the lights, rain every other day thru summer and it looks like housing wires around the bulbs is not waterproof. I took a dremel tool with a general cutting bit and tightly cut around the line that meets with the back of the bumper. Was a little tricky and took my time, had to sand the edges a little in the end, but looks good now and still covers the fog light backs.
