I had a rock go through my passenger fog light so I ended up finding a replacement light on ebay. It was from an aftermarket company but was a lot cheaper than the ones from nissan. It fit great but I installed my new piaa's at the same time as changing out the fog light and now 2 days later, the lens is cracked. I am guessing it's from the heat. The stock fog light is fine though. Has anyone had this problem before?

 

I had the same problem. Did your aftermarket foglight have "Depo" imprinted into the glass instead of "Nissan". I had Lamin-X on the foglight and it turned brown after a few days of use, then the foglight lens cracked. I also have PIAAs in them. My OEM foglight also with Lamin-X has not cracked or turned brown. I think the aftermarket foglight cant handle the heat from the PIAA bulbs light the OEM foglight.

 

Both of my OEM fog lenses cracked just days after installing PIAA"s...
This guy's opinion... Heat!

 

I had the same problem as Mizike.

 

my guess is that the aftermarket one has a thiner lens and cant handle the heat or is made from glass instead of plexiglass. if you take a water glass and put hot coffee in it it will crack. i was looking for a fog light for my car because its cracked and found some for good prices. http://www.autobodypartsonline.com/c...10105423290.67
