Do these headlights work with the original F150 wiring harness?

These are designed as direct replacements and mount at factory connection points. Confirm connector compatibility with your vehicle before installation—some minor wiring adaptation may be necessary depending on your truck's specific electrical setup.

Will the black finish hold up to UV exposure and weather?

The blacked-out housing is built into the assembly itself, so it won't peel or fade like a coating would. The finish is integral to the hard panel construction.

Can I install these myself or do I need a shop?

You'll need basic hand tools and access to the front end. Since they bolt at factory points with no cutting or drilling, DIY installation is possible if you're comfortable working around electrical connectors and removing the OEM assemblies.
