This winter several American states are reporting that LED traffic lights are so energy efficient that they don’t produce enough heat to melt any snow that covers them. And this is causing accidents. One of the side effects of the previously used incandescent light bulbs was that they would melt any snow that covered them.

So the new LEDs have caused a few accidents and even a death is being blamed on them. Not to worry though, a fix is being worked on. I’m surprised none of the engineers thought of this problem before hand.
