I noticed something over the weekend that all you "southerners" don't
have to deal with.
Pretty much all traffic lights are now high output LEDs. Saves energy
and they last a long time, but there's a problem.
After a wind swept snow storm with heavy wet snow that then freezes like
we had Friday, the lights become completely covered and you can't see
which one is on.
The LED's aren't hot enough to melt the snow away like the old fashioned
incandescent types, so even 24 hours after the snow stopped flying you
still can't see which of the lights are lit at many intersections.
Causes quite a bit of confusion until people realize what the issue is.
We have some type of heating element in the light to keep it from freezing over. Yay Virginia DOT.

I guess we are not the only ones with this problem:
