I drove back from the North on Saturday, down the M6 in torrential rain. I think for a time I put the front & rear fogs on because the weather & visability was so poor. Then I hit a puddle of standing water that jolted the car. I wonder if the hot lenses + cold water caused the smash?
One lens has completely gone, the other has a crack that runs the circumferance of the lens. It looks like the sort of crack that happens if you put a cold glass in a hot sink.
I really doubt foul play. Also, when I mentioned heat as being a possible cause, I didn't think that it would be the sole source, but I think the heat + rapid cooling might do it. (I didn't think that they'd melt under the heat of the bulbs, I'm not THAT stupid!)
