The new headlights complete the different look of the front end. The lights are a pain to adjust. You have to adjust each light individual and at dusk or night and you can't install because they adjust from the rear. It would be better to find a wall, park 20 feet back and aim 3 feet high, but that's hard to do. The looks are worth the trouble though.

I thought the headlamp was easy enough to install, but the wires for the led lamps was a surprise and difficult to install. I think it would be easy to connect the leds internally and eliminate the wires. Also, there was no wiring diagram to show how the wires were to be connected, so I had to call the supplier.
