Makes sense, but wouldn't it be cheaper to stick a motor on the light to vibrate and detach the snow/ice?

In cold weather a car windshield can ice over at 60mph without defroster heat, I don't think a vibrating light housing will stop freezing rain from building up.

There is one thing that is proven to work in a wide variety of situations, is easy to supply, has no moving parts: heat. And there are already solutions out there to provide heat.
