Do these bolt directly to my truck or do I need custom brackets?

These mount at factory headlight locations — no brackets or drilling required. Bolt them in place using existing mounting points.

Will I need to replace wiring or can I use my current harness?

LED units typically work with factory electrical connectors, but confirm your truck's connector style matches before ordering. Test-fit one unit first if you're unsure about compatibility.

Are these weatherproof or do I need to seal them after installation?

LED reflector units are sealed against moisture during assembly. Once mounted securely, no additional sealing is needed — just ensure fasteners are tight and the gasket sits flush.
