Will these plug straight into my factory fog light wiring?

These mount at factory fog light points, but electrical integration depends on your truck's harness. Test-fit the housings first, then verify bulb type and connector compatibility with your existing wiring before final installation.

Do I need any special tools or brackets to install these?

They're designed for direct bolt-in at factory mounting locations. You'll need basic hand tools and a test fit to confirm bracket alignment with your bumper frame.

Can I paint or modify the black housing?

The housings come finished in black. If you want to modify the finish, prep and mask carefully to avoid damaging the internal halo ring components.
