Problem with LED traffic lights following snow storm
Posted on December 11, 2009
GREENFIELD - The recent snowfall has exposed a problem with new energy efficient stoplights in some communities.
The LED were installed as a way to help save money on energy costs, but the lights are so efficient that they aren't generating enough heat to melt snow and ice on the traffic lights.
As a result, drivers can't tell what color the light is or if it is even on.
The problem is further exasperated in Greenfield because the stoplights have fin-like grates, which are meant to direct the LED light beam, and snow tends to get stuck in them.
Crews then have to go in and individually remove the snow and ice from the lights.
