Do these mount at the factory cab light positions?

Yes. These are direct replacements that mount at factory rocker points — no drilling or bracket fabrication required. Remove the old housings and swap these in.

Will these work with my truck's existing wiring?

These are designed as direct bolt-in replacements, so they integrate with factory cab light circuits. Test-fit to confirm connector compatibility before final installation.

Can I return these if they don't fit?

Check the return window posted in your order confirmation. Cab lights are direct replacements, so verify your truck's year and cab configuration before committing.
