I picked up a set up Xenon Fender Flares for my '03 Jeep Wrangler Rubicon.
I love them. They are very easy to install, and include all the hardware needed. They replace your side markers/turn signal lights with a very low profile lens built into the flare. All you have to do during the install process is snap the light assembly into the fender flare and plug them into the factory plugs.
They do a great job of using factory holes for the install, so you don't have any drilling to do.
The end result is a good looking flare, that's great for offroad.
Some of my favorite aspects of the Xenon Flares for Wranglers:
In my opinion they look even better than the stock Rubicon fender flares, and do a better job offroad. For the money (about $350.00 for a set), they are well worth it. I picked mine up at 4 Wheel Drive Hardware in Columbiana Ohio. They matched the price I found online.
