i had a lund visor on my 96, and i actually go going fast enough that the visor caught enough wind that it came up a little and the top of my cab pushed down. luckily when i slowed down it went back up. now on my superduty i just have cab lights. they are much brighter any way. i have put 3 sets of the cab lights on, they are not hard to install. you can get all the lights and the harness to plug them in for 80-85$ from ford. the harness just plugs in on the passenger side kick panel
