There's another thread here where the OP states he's having issues with LEDs. Specifically, they don't get hot and therefore allow snow to accumulate and form an 'ice lens', and extremely limit forward vision. The vehicle he's having an issue with is a new GMC Sierra. FWIW, my boss just got one (2021 GMC Sierra) and has the same problem. GM dealer is clueless.
I read the thread. Has nothing to do with LEDs and everything to do with vehicle design. Any flat faced light collects snow/ice...especially when heavy. You know how many Jeeps ive had throughout the years that had the same issue...with halogens??? Yes it sucks, but you stop when you can and wipe them off. Or use something like rainx, which doesnt do a whole lot in the heavy stuff. FWIW id not use Pam or other spray oil, itll degrade the headlight eventually.
