Folks,
For the second time in 1 month, the left side fog lamp has cracked and it looks like a rock hit it

I was wondering what the chances are of that happening because I was thinking - TWICE??? IN ONE MONTH?????

Anyway, got stuck the first time with a $170 bill for the foglamp because they have to sell the whole unit and not only the cover ... now another $170???
Has anyone out there experience cracks multiple times on the same foglamp?
Could it be stress fractures or something??
Also, is there a cost-effective solution for this - other than having Trasco build me a bullet-proof foglamp
