So would about $300 for performance and $480 for aesthetic styling be accurate?
I would probably judge it about $400/$280 respectively, as that is what I paid for mine.
To me, as someone who uses my headlights quite a bit, the money is negligible as the beam output on them are absolutely fantastic, which I prefer compared to the TLs. Considering the quality as well as the money saved by not worrying about bulbs, $680 is simply a drop in the bucket compared to what most people spend on their rigs.
I have them, I love the light output, no blind spots, see forever....
As to flicker, it is not noticeable enough to think about, at least for me, for now. The flicker seems to be related to the age and condition of your battery. Mine is fairly new so little flicker. When the flicker becomes noticeable I will go to the harness direct to battery. Susquehanna Motor Sports among other suppliers.
I have had the headlights for over a year and just installed the new foglights. I have to say spending almost a grand on these lights was well worth it. Others will rip about spending so much but when you are either off road or back roads at night it is well worth it. Turn on the fogs at night and it fills in everything below the headlights and floods out to the sides to light up debris, ditches and holes. So I highly recommend them.
I'll spend way more for the Rigid's that i'll only use off road. These I would use every night. Seems expensive but in the grand scheme of things "Jeep" it's a cheap mod. I think 680 seems higher than what JPi quoted me. But I will have to check on that.
