Will these bolt straight to my Cascadia without any wiring modifications?

These mount at factory fog light points on your cab. Confirm your truck has factory fog light provisions before ordering — some model years have blanked-out mounting locations that require drilling or relocation.

Do I need to seal these after installation to prevent water intrusion?

Chrome housings are designed as sealed units. Once mounted at factory points with factory fasteners, water entry is not a concern. Use stainless or corrosion-resistant hardware if re-securing.

Can I return these if they don't fit my truck's year?

Returns follow standard policy. Verify your truck's year and model before checkout — fitment responsibility is on the buyer. These are engineered for the specified model year range only.
