It seems like it's something new every week

...
I noticed today after parking for the night that the right lens on my Bosch euro headlights got a huge chip in it today. I didn't notice any rocks hitting the car, but who knows what I'd hear that far forward on the car with the radio going and road noise at 70mph. It's a pretty big chip...looks like the type of chip that happens when a window is hit with a BB. Sort of glad the object didn't come up and hit the windshield (it was really close to going over the light and hood). Even though my insurance would cover a windshield replacement, I don't really want to go through the headache of a possible bad windshield and/or seal plus the time to get it replaced.
Anyway, to the point...does anyone know where to get genuine Bosch lenses for W124 euro headlights? I'll probably end up doing both since the ones I have are pretty pitted.
