What size lights do you have?
There are options for 7" round and 5"x7" that range from very good to excellent.
The drop-in replacements from unscrupulous companies like Lifetime LED are not legal and don't/can't work properly.
I've tested and used:
Trucklite Phase 5, 7"
Trucklite Phase 6, 7"
Trucklite Phase 7, 7" & 5x7
JW Speaker Model 8700 7"
JW Speaker Model 8700 Evolution, 7" and 5x7
JW Speaker Model 8700 Evolution 2, 7"
I'm on my second set of the Evo-2s, beta testing the new adapter for use on Jeep JKs (needed for their pulswidth modulated power delivery to the lights)
The JWS Evo-2 is the benchmark right now. I haven't tested the Petersons yet (also sold as KC) but I've seen the photometry and it's very good. The TruckLite's are also good, better in their ECE rendition; in their SAE trim they produce some "artifacts" that many users are distracted by.
I have to add the Evo-2 to this mess but I started all the testing with TL Phase 6 here:

And no, they don't melt snow well. The original JWS Model 8700 did. It had a fan and a glass lens.
And I've heard that there is a Trucklite version of their Phase 7 designed for snow use but my contact at Trucklite has moved on and I've never seen this white unicorn...
BTW, the Trucklite Phase 7 is also sold as a GE branded product. Shop around.
