Do these lights use the factory wiring harness, or do I need to run new wire?

Wiring configuration is not specified — verify your truck's existing fender light connector before installation. Most direct-fit kits use factory harnesses, but test compatibility before committing.

Will I need bolts or adhesive to mount these, or does hardware come in the box?

Hardware is not confirmed in the kit contents. Have M8 or M10 hardware on hand in case fasteners are required at the factory mounting points. Confirm mounting method during unboxing.

Are these lights street legal, or are they just for show?

Regulatory certification is not specified in the product data. Check your local lighting codes before installation — some jurisdictions have restrictions on fender light brightness and color.
