I love your analogy of not staring at the signs like a bug!

Yes, they glare off some things but that is because they put out lots of light.
The halogens in my last jeep were like little emergency camp lanterns using tealight candles. I put led replacements in it and did not look back (despite all the half blind people that think that they have some magical power to bend light differently and this is why they have trouble seeing, can't be their cataracts!).
For snow or ice build up, why do the LED lights have heat sinks to dissipate heat if they run so cold? I just never had a problem with them.
