Don’t have an actual temp. They get hot enough you wouldn’t want to hold onto them too long, but not so hot they’d burn you.

No idea if they melt freezing rain, but I just drove home in a blizzard and they did great. I’ll have to put my hand on the lens some time and see if it’s warm.

Mine have lasted well over a year. I carry 2 halogen bulbs in the foam lined box the LED’s came in, just in case. Still waiting.... I guess if they freeze up in freezing rain I could toss in the halogens.

Honestly I kind of expect the resistor to fail first. But it’s not critical to operation and I have a spare.

I was buying $45 halogens every year and a half or so. These LED’s are not much more and if they only lasted a year I’d be happy.
