Do these bolt directly to the factory bumper, or do I need to modify anything?

They mount at factory points with no drilling or permanent modification required. You'll want to test-fit before finalizing your wiring run to confirm harness routing.

What wiring and connectors come with these lights?

The assembly is included. Verify your existing bumper harness connectors match before ordering, or plan for a small adapter if needed — exact connector type not confirmed in stock specs.

Are the lenses sealed, or do I need to seal them after install to avoid condensation?

Lens seal condition not specified — treat them as new units and inspect the gasket before installation. A small bead of silicone around the housing after mounting is common practice for moisture prevention.
