I believe that if you were to examine the lens cover very closely, you may find in fact that there are very small fissure like cracks on the inside. There is no way to get rid of these. I used a product from Bavarian Motor works $39.00 and it caused improvement in the neighborhood of approximately 20%---although not good enough to my liking <img src="/forums/images/graemlins/oink.gif" alt="" />

I later replaced both lights at about $100.00 each. I also discovered that the "new headlamps" were made a little differently (WOW go figure)! They appeared to be made better in the quality of material. I also believe that they will NOT tarnish.
