Do these plug directly into my factory wiring harness?

Yes. These use the OEM electrical connectors and mount at the factory attachment points—no rewiring or adapter harnesses needed. Plug and play installation.

Will these work with HID or LED bulbs, or do they come with bulbs?

Bulbs are not included. These assemblies accept standard H11 low-beam and H9 high-beam bulbs; you can upgrade to LED or HID aftermarket bulbs if you want. Check fitment against your preferred bulb type before purchase.

Are these sealed against water and condensation?

Sealed lens design keeps moisture out under normal driving conditions. Heavy water crossings or pressure washing directly at the lens may compromise the seal over time—use caution.
