Frequently Asked Questions
Do these bolt straight into the factory fog light openings?
Yes. These mount at factory points with no drilling or bracket fabrication. Your existing wiring harness may require a simple adapter or relay harness depending on your truck's current electrical setup — confirm your current fog light wiring before installation.
Will I need to reprogram anything after installation?
Depends on your truck's module configuration. Some Cascadias recognize LED assemblies automatically; others may trigger a warning light. Have a diagnostic scanner on hand or plan to visit a Freightliner shop if the dash throws a code after swap.
Can I return these if they don't fit my specific truck?
Contact our support team with your truck's VIN and current fog light setup. Fitment can vary by production batch and electrical configuration even within the same model year range.
