Are LED Traffic Lights Safe in Winter?
LED traffic signals are great alternative to traditional incandescent signals.
use 80 to 90 percent less energy
last 5 to 10 times longer
increased replacement interval
unlikely to fail all at once
However, LED traffic signals cannot melt snow!
One of the great advantages of LED traffic signals is that they do not waste energy by producing heat. The surface temperature of LED traffic signals only mark between 10 to 20 °C (50 to 68 °F), while incandescent lamps hover near 45 °C (113 °F).
This advantage, however, acted adversely in some snowy scenarios as the LED traffic signals were unable to melt away accumulated snow.

The Unexpected, Potentially Deadly Winter Problem of LED Signal
Snow-covered traffic signals pose great safety threat to motorist and pedestrian. They cannot navigate safely when LED traffic lights are obscured by snow. Numerous accidents have been reported in North America.
Most cities resolved to manually clean off the snow, posing safety hazards to work crews as well. Also, snow removal job requires additional cost. → Labor intensive, time consuming and waste of budget.
Numerous attempts have been made worldwide to solve the shortcoming of LED traffic lights.
They include changing the shapes of the lenses, attaching additional covers, and applying special surface coatings. But none of them has provided definitive solution so far.
