I've already had one headlight replaced due to this fault, and now
it's happened to the other one.
I've tried putting dessicant behind the headlight - in the area
exposed when the rear cover is unclipped, but to no avail. The
headlight stays cloudy, the dessicant stays dry.
Surely the unit can't be so well sealed that the dessicant can't "see"
Where does the moisture get in anyway?
