While the heated Trucklites should work, you could also just consider some Cibie lamps, H4 bulbs, and and a new wiring harness. Quality incandescents still produce exceptional light and of course do melt off snow.

I went with the JW's and i find them to be great so far

I just purchased a set of JW speaker LEDs. I should have them by next week, hopefully they'll be ok in the snow and ice.

A guy over on JKOwners.com did a pretty good temperature test, and it appears that they should melt light snow.
