Do I need to remove the grille or bumper to install this?

Mounting at factory points means minimal disassembly. You'll likely need to access the headlight bucket from behind the grille opening or bumper area—check your truck's specific access points in a service manual to confirm your exact removal steps.

Does the bulb come with the headlight?

This assembly ships without bulbs. Your original bulbs should transfer over if they're still good—just verify they match the style your truck uses before installation.

Will this work as a direct bolt-in, or do I need sealant?

Factory mounting points ensure alignment, but seal the perimeter with automotive-grade sealant or gasket material to prevent water intrusion around the housing. Don't skip this step—moisture inside the headlight kills the lens fast.
