Lighting is not only functional but also really helps the looks. I went with the Hella 500 fogs first and mounted them on the TJM to take the place of the stock ones as they went with the stock bumper.  It was actually quite convienent to not have to run wires or anything.  I just used the stock wiring and that was that.  I just got four driving lights and mounted them on my basket.  I am going to wait to wire them up until I head home and get some help from my father who is obcessive about quality and fit and finish and but also has every tool known to man.  I also have some el-cheapo fog lights that I picked up from Advanced Autoparts mounted on the rear of the basket as auxiliry back up lights.  I'm going to wire them up with a three position switch so I can have them On, Off, and Auto so they come on when in reverse.  My next lighting mod will be some rock lights.  Rock lights are basicly functional under glow that doesn't have any color.  When off roading at night you have to be able to see whats going on under the truck and thats their main purpose.  I want to also tap into the Interior lights so they will turn on when a door is opened.  Perimeter lighting taken to the next level!  I'll post a writeup when I get around to installing everything.  As for the headlights I have Silverstars and love them.  There have been scientific studies done on the fake hid bulbs and the stilverstars had the most light emmited and also had the lowest glare.
