I received a PM about the horizontal headlight adjustment screw I added, so I figured I'd post it in here even though there is a writeup or two out there somewhere. Head to your dealer or order part number 55078114 which I think was around $2 each. You'll want to order 2 so you have 1 for each side.
You first pop off the grill with the plastic pop rivets (I snapped one so it's nice to have a spare) and remove the headlights from their buckets which requires a Torx / T-15 driver. I bought one that looks like a thin screwdriver to make headlight adjustment easier since the ring is held on by the same type of bolts as the adjustment screws. After you remove the headlights, you'll see the vertical adjustment screw in the upper left corner and the fixed post bolt in the diagonal corner below:
Use a 15mm crescent to reach behind the bucket and loosen it until it comes out. It takes a little bit to work it out since you have a small range to work with.
This is what the bolt looks like once it's removed. You can see the rim/crown of the bolt at the end where the bucket snaps into place over top of it.
This is what the replacement screw looks like:
Simply replace the fixed bolt with the new one. Although the threads are different, the new adjuster screw goes in without any issue.
Repeat the same on the other side, and be sure to aim them on a flat surface in the dark. I'd suggest keeping the Torx driver in the Jeep with you for a while until you get the aiming fine tuned. Fortunately because Euro Jeeps have the horizontal adjusters, the grill already has the cutout for you to put the driver in without having to remove the grill. I would HIGHLY recommend if not flat out say it's a necessity to add this adjustment to any LED or HID aftermarket headlights. You're not only not getting the proper light down the road, you could very well be blinding other drivers without full adjustment. It takes a bit to dial in properly, but it's absolutely worth the time and very minimal cost.

I have been looking forward to the new JW Speaker 279 J tail lights however, and they finally started shipping about a week ago. I picked up a pair from my favorite local retailer High Country 4x4 and installed them this weekend.
