When I came back this summer to my GN, my passenger side light was like this, but still worked. I have the SilverStars, so I was a little unhappy to see I needed to replace one already. What happened with mine is, water got in somehow (no chips or openings) and must have washed off the reflective material (paint) that is in the back of the headlight. I noticed this when I took the headlight out and could see my hand holding the headlight on the back side.
