As for the underglow. I figured a way that looks really good. I went to my local electronic shop and bought some tiny squar lookin LEDs and wired them up in a line and placed this offclear fuel tubing through it and when wired to the truck instead of looking like spot light on the bottom of your truck it's more like a glow. NOTE i did have to use 300OHM resistors on my LED for a 9V battery. Anyone need the Schematics for it let me know. Right now I'm working on a third brake light for my MAXX
