Do these lights bolt straight into the factory cab locations?

Yes. These are designed for factory mounting points on Super Duty cabs from this generation — no drilling or custom brackets needed. Just remove the old light and bolt the new one in place.

What kind of wire connections do I need to make?

Mounting method and electrical connection details are not specified — test-fit before committing to your wiring approach. You may want to verify the connector type matches your truck's harness or plan for a simple splice if needed.

Will the smoke lens be dark enough to see through at night?

The blue LED is bright enough to illuminate the cab interior; the smoke tint reduces glare and glint without blocking the light output. If you're concerned about visibility, order both and test-fit one first.
