The laws of unintended consequences is in play here. A good idea to save
energy that does not work as intended in a cold climate.

My DOT buddy told me this is not as much about saving energy as saving
maintenance. The LEDs are supposed to last a whole lot longer. A
heater running at a low power would last virtually forever too and
they can be controlled thermostatically so they would not run at
ambients over 40 or so.
