I called the manufacturer of the light today and was very helpful (I could not have asked for better help) When I took the lense off we discovered the installer (Keystone) did not put in a supplied O ring around the lense. Water apparently got in while we were in Fla and fried the circuit board. I talked to Keystone and they would not commit to a repair without an inspection by a Keystone dealer. The problem is that if it is NOT approved, I'm on the hook for the dealer diagnosis $$. I've decided that it's just not worth it. I can get a regular light for less than $10 and replace it myself. If you have this light in a Keystone unit you might want to check to ensure the O ring was installed.
