In no way is it overheating from the lamps or engine. Several reasons its not foggy and hasnt been foggy enough to have them on for long enough to shatter through heat (even if your a foglight numpty and have them on all the time there is still no way enough heat can develop). If it was heat from the engine then the plastic bumper would have melted long before the glass foglights. Add to that the following taken from Encarta:-
"Depending on it's composition, some glass will melt at temperatures as low as 500 °C (900 °F), others melt at 1650 °C (3180 °F)"
Do you think your engine or Foglight bulbs are capable of producing that much heat? Dont you think your plastic intake/pipework/ancilaries would have melted long ago at temps of
900 °F let alone 3180 °F?
Flexing of the bumper will not do it either as the lamps are VERY solid units and do not flex in any way and are not a solid part of the bumper. Push the bumper and it will move but it will not "flex" the lamp in anyway. In fact the glass being solid is the very reason it will shatter before the bumper will, if a ston hits the bumper hard the bumper will obviously flex. The glass light will not, hence very easy to smash a bulb.
Sorry to say but think you are either looking at an extremely unlucky drive or vandals. We had a series of foglight smashes in our area, culprit was caught and admitted targeting cars that always had them on. Guy next door had his smashed, I did not (This is a worst case, but these sort of idiots do exist unfortunately).
