I had a set of Trucklite 7" LED headlights on my Jeep JK for 10 years and LOVED them. I just hopped on Quadratec.com (Jeep parts outfitter) and they still sell them and they are still highly rated, and are just as expensive when I bought mine--a relative value over time..lol. Models by JW speaker are also highly rated. I see a lot of guys running around with the Oracle brand lights which are significantly cheaper. Lots of brands have come a long way since way-back-when.
In 10 years of use, not a single issue with the headlamps themselves. One of the PWM harness connections (plug and play) was maybe loose or something and causing issues with one of the headlamps once. Wiggling it replicated the issue. Disconnecting it, cleaning the terminals, and reconnecting with dielectric grease solved the problem.
You will need the set of PWM (pulse width modulation) harnesses to eliminate flickering of any LED headlamps. Sometimes they are included and sometimes they are sold separately, so just beware.
Sadly but gladly, I sold my JK last week, and with it, the LED headlamps. I brought home a new Rubicon XR which has an LED lighting package from the factory. It's quite good!
I highly recommend both of these online sellers:
Quadratec.com
Northridge4x4.com
