Frequently Asked Questions
Q: Are fog lamps included? A: This listing identifies the wiring harness and switch kit; do not assume lamps are included unless shown.
Q: Will the dash indicator work? A: Factory indicator behavior depends on the truck wiring and control module configuration.
Q: Does it fit a 2007 new-body Silverado? A: The listed range is 2003–2006 plus compatible 2007 Classic, not the redesigned truck.
Q: Why use a relay? A: A relay lets the switch control the lamps without carrying full lamp current through the switch.
