Do these mount at factory rocker or mirror points?

These are designed to integrate into your OEM towing mirror housings. Install method details and exact mounting points should be verified during test-fit before final assembly.

Will these lights stay stable at highway speeds?

Chrome-housed LED markers are engineered for full-speed stability once properly mounted. Make sure all fastening points are secure and test at low speed first.

What electrical connection do I need?

These lights tap into your vehicle's existing side marker wiring. Check your Super Duty's electrical schematic to confirm wire locations and gauge before cutting into any factory harness.
