How does snow and ice affect the bulb life? If it makes it hotter I would expect the snow and ice to melt and be a non-problem.
Agreed, I would sooner chalk it up to the bulb ending up with water vapor in the reflector housing, freezing on the bulb and causing uneven expansion during the rapid heating at first power on, though personally, I don't encounter many bulb failures and have snowy icy winters every year, but I do wipe snow off if the lights are going to be on, 'cuz they're not very effective if snow is blocking them, lol.
