Well today after 2 years of ownership I found out the SLT's are prewired for fog lights, so I bought the kit and installed them tday. I can't believe how easy the install was. Only took about a half hour to install and about ten minutes of adjusting and presto..... MORE LIGHT. Might throw some Silverstar Ultras in for some whiter light.

 

I am a believer in fog lights. They really make a high sitting truck see better. (and they look cool too)
