Those are modeled after the military LED tail lights in use today. The small ticks are the black out lights. The row of 4 is the black out drive light and the row of 2 is the black out brake light. Black out lights are used when driving with NVG's.
I acquired a set of the tail lights and was going to do something similar using Rugged Ridges steal light housings. Keep in mind with the price of these (and I do agree they're expensive, I also agree most things for the JK are over priced when compared to previous wranglers) that you're getting the LED lights (they're not cheap), a wiring harness, and a new housing to mount it all up. For my Jeep I decided to go a different and cheaper route. Also, in comparison a pair of replacement factory lights are going to cost you almost 300$ from the dealership.
I don't find anything wrong with the factory lighting except the rear tail lights are prone to being damaged and pricey to replace. Truck-Lite LED head lights aren't going to do anything for me over the next 10-20 years that my stock lights won't. I actually wish we could go back to the dim head lights of the 80's and 90's because it would sure make driving alongside oncoming traffic far less painful.
