Will this mount using the factory cab light location?

Yes—this is engineered as a direct replacement for the OEM cab light. Your existing mounting points will accept this assembly without drilling or modification.

Do I need to do any wiring, or does it plug in?

Wiring specifics aren't detailed in the product data—test the connector at your cab light fixture before committing. Most direct-fit lights use the factory harness, but always verify compatibility with your truck's model year before installation.

What's the difference between the smoke housing and a clear one?

Smoke tint reduces glare and nighttime brightness intensity, giving a more refined appearance while the blue LEDs still deliver solid cabin illumination. Clear housings are brighter but less refined—smoke is the move if you want a finished look.
