Quality engineering at work
This is an example of some very well thought out engineering. You know those LED traffic lights that are popping up everywhere? Nice and bright with a really low power draw? Well guess what? That low power draw means that the bulbs no longer produce heat. THAT means that the traffic lights don't melt the snow that drifts into them, an issue that was never a problem with the horrendously inefficient and hot running incandescent lamps. This means that the colder states are now seeing crashes, and apparently even one fatality, as a result of the snow blocked lights. Fun!
