I added 14+ Pro4x wheels with new 275/70R16 BF Goodrich KO2s last month. Shortly after i added a bull bar with a 20" light bar. Wired in a custom switch I found online. It matches the interior lights and is wired so it will come on with them. Whenever I turn on the light bar, a green light comes on illuminating the "light bar" words. I love it. Everything makes my truck look so much better!
