LED traffic lights and LED sidewalk lights don't put out any heat to

up rigging up some way to keep the ice and snow from obscuring those LED
lights, where is the energy savings? Last Winter, in some parts of
America, they had trucks going around and spraying deicing
fluid/whatever kind of fluid on some LED traffic lights.Not much savings
(Money) there either.

I cannot speak to traffic lights, because they are necessarily aimed
sideways into weather from *some* direction - but for general
illumination, all you need is a housing that keeps the snow and ice
off them. Not that hard to construct, and would serve the double
purpose of eliminating light trespass and light pollution.
