So I bought these yellow aftermarket oem fog lights off ebay for my 1999 honda civic. they look great and give me extra visibility driving home from dark highways. But the glass lens on my right fog light cracked. Could this be due to rocks from highways? I do drive at about 75mph+ on highways. Or, could this have happened because of the heat from the bulbs? The crack splits into three directions, like a mercedes emblem. though, i don't seem to see any significant chipped glass on the lens. just curious. any suggestions?
