The moisture problem was causing the circuit board in the led light to short out and the power circuit had a 10 amp fuse in it. The results in some cases was a fire or melting of the clearance light, which produced smoke inside the motorhome. The led lights used are made by Command. The fix added a 1 amp fuse to the wire supplying power to the cap mounted clearance lights so it would blow if any of the cap clearance lights developed a problem. Not a fix of the real problem, but it prevents a fire.
