Re led bulbs - wasn't there a problem up north when they changed all the stop lights to led and in winter they filled with snow so they couldn't be seen because they don't put off enough heat?
Yup - 1st generation technology problems.
You can actually buy them as surplus. They must have put a heating wire in the cover lens - same as a rear window defroster - to fix the problem. Or something like that.Very much not the same thing as a home light bulb though. Light is waaaaayyy up there and the power supply for it is waaaay down here on the ground - where any heat the power source generates isn't gonna help.
