i actually tried making a light bar for my last truck and i got a piece of tubing and bent it myself to follow the curves of my bumper. i still have it sitting in my garage. i like number 2, put two hid offroad lights in the middle and myabe two duallies on the side and be done
i think 6 is the best. it takes the best of a prerunner (tube look) w/ the style of factory bumpers (can't see all the mechanics to the truck, makes for cleaner look).
