I bought these headlights to replace the weak stock headlights on my 2007 Jeep Wrangler. After the time of fiddling and installing I am very happy with the purchase! Advantages: Better light output than factory. The halo headlights look crisp and the halo turn signals look sharper. Clean look with black body, looks almost like factory. something odd, like some sort of electronics added to the CAN-BUS system. The packaging was surprisingly nice. The headlights have H4 connectors and contain CAN-BUS decoders with H4 input and H4 output. They contain an H4-H13 connector that plugs into a decoder. The supplied H13 plug does not fit into the factory outlet. I had to cut some plastic and secure it with zip ties. It holds up well, but for the extra money it might be worth buying a better quality H4-H13 CAN-BUS decoder. Halo bulbs are easy to install, but you must connect them to the factory wiring harness. Instructions are included, but there's a surprising amount of support on forums like JKOwners, and even installation feedback here. Verdict: If you have a day off and are mechanically inclined, this is a great buy. If you're afraid to mess with splicing electronics, you can always install ghosting and not use it, or buy a non-ghosted version. The total installation time for me with basic tools, soldering and fastening connections was about 1 hour. Also a nice tip for confused people: On the headlight, the green wire is the turn signal wire, the red is the tag. light of time. When you connect the Halo to the JK's turn signals, the 3 wires coming out of the turn signal bulb are the black wire which is ground, the middle white wire is the parking light and the far white wire is the turn signal wire. I connected the white halo (red wire) to the parking light and the yellow halo (green wire) to the turn signal wire. install as I couldn't find anything on youtube and find these videos very helpful to make such purchases
