After having done the headlight upgrade in the ZJ, I've been thinking more and more about lights for the Scrambler too. I've been siting on some conventional H4 housings for years (since the original Scrambler build order in 2007) with the intention of installing a separate harness, but aftermarket headlights have come a long way since then. I've unintentionally acquired another set of H4 housings too, but I'm not sure I'm going to use any of them. The JW Speaker/Vision X/TruckLite 7" LEDs have always bugged me by how they looked, but if we're talking about moving away from a stock look, then we also need to talk about the Morimoto Super7. The quality of the M-LED 2.0 in the ZJ has been mind blowing. The last time I drove the pass it was a clear night, so I really tried to stretch my eyes on the straightaways to determine what the useable distance was. I was also really hauling a$$ since the engine tuning is done, traffic was light, it was in the teens and twenties (so actual consistent packed snow and ice rather than melty glare ice with a layer of water on top, or recently re-frozen ice, or worse yet re-frozen ice with a thin layer of whispy snow on top). I was able to "see" around 30 seconds down the road, which meant over half a mile going 70-80 mph. It was at a point where I was looking so far down the road that I started missing what was actually right in front of me, and I had to refocus my eyes on the immediate next couple hundred yards instead of watching for moose that were still 1/4 mile+ away.
A buddy of mine installed the Morimoto Super7 in his TJU, which uses the M-LED 1.0 projector integrated into a 7" housing unit. While the M-LED 2.0 is a definite upgrade (particularly in terms of width) over the 1.0, the original is no slouch either. And I'm no more offended by the look of the Super7 than I am by the JW Speaker/Vision X/TruckLite style. (Morimoto also makes a version of the same light sold as the Sealed7. I expect it's of the same quality as the JW Speaker/Vision X/TruckLite light.)

He's reported no problems in snow/slush with the Super7. I was also concerned about it with the projector conversion in the ZJ, but the M-LED runs hot enough that it requires an integrated fan with the heatsink. While it's still cooler than an HID projector, I figured that the fan running inside the ZJ housing that it would at least prevent serious accumulation. Well, on the last drive back, we had wet heavy snow at around 30 degrees, and sure enough, it froze up. But it froze up EVERYTHING. I couldn't keep the ice buildup off of the windshield wipers either even with the defrosters on full, and it was packing in on the edges of the H3 fog lights too.
People up here who have the heated TruckLite 7" lights have reported that they'll still do the same thing in those conditions, and they otherwise end up baking the road grime onto the covers. Owners of the new JLs with OEM LED headlights also report no significant adverse issues with snow/ice packing up (except in the conditions described above), and I don't believe the JL lights have heating elements.
