headlights

That's pretty much the extent of it; subjective impressions of headlamp performance are not reliable because the human visual system is a lousy judge of its own performance. In plain English, it's really easy to create situations in which we think/feel we can see way better or way worse than we actually can.

The '07-up Wrangler headlamps aren't dangerously bad or anything; they're adequate (and easily available; a lot of Wrangler owners take them off to put on Cibies so they can see better at night!). But (again) they're poorly focused. If what you want is a clear-lens headlamp with a "jewelled" reflector, there's a much better option; see discussion here. If for whatever reason you decide to go with the Jeep lamps, use only genuine Chrysler-made ones. The aftermarket lookalikes are all garbage -- even cheaper and sloppier than the genuine units. Most of the aftermarket lamps don't even come close to meeting DOT specs, but they all claim "DOT/SAE approved" and "OEM quality". :roll:
