Does this come with the halogen bulb installed?

Assembly comes complete and ready to mount. Bulb installation and any future replacements follow your vehicle's service manual — no special tools needed.

Will this headlight work with my vehicle's existing wiring harness?

This assembly connects directly to factory harness connectors with no modification. The original plug and socket remain unchanged.

What if the headlight doesn't work after installation?

Check the bulb first — verify it's seated fully in the socket. If the bulb is fine, test the wiring at the connector using a basic multimeter to confirm power is reaching the harness.
