Re the Halo's. I ordered the kit from Oracle lighting. Advanced Automotive Concepts- AACstyle.com
I ordered the kit for a 2013 JK I dont recall measuring the halo diam but I'm sure if you call them they can tell you that info. Btw, i used their color shifting kit which I highly recommend. You can change the color on the fly to almost anything and add effects such as strobing. The cost of the entire kit was a lot less than it would have cost me to whip one up from scratch, and there was no time involved. The harder part was removing the lenses from the JW Speaker head and fog lamps, which is very dooable, but tricky the first time around. There are no brackets available for the 6145 and the 10A bumper. Get the 6045s or take it to fabricator for custom brackets. Ultimately, I did the latter because I had already converted the fog lamps prior to realizing there was a bracket issue.
