Will Your Plan Melt Snow?

I came across a funny article in my nerd reading:

This winter, we as a nation found out that incandescent traffic lights emit plenty of infrared heat through the colored lens—enough to melt drifting snow that otherwise would accumulate, obscuring the lens. Wonderful new, energy-efficient LED traffic lights do not emit that much heat.

It’s not a huge problem that the new LED traffic lights don’t melt snow. When it’s snowing that badly traffic usually slows down enough that turning a stoplight into a stop-sign is just an inconvenience. Research, new technology, and improvements are good. Keep them coming. If you want to produce a great product though, plan for it. Mentally put your stoplight out in the snow before you build it. Be just as proud shipping to India as you are shipping to Wisconsin.
