Does this come with the HID bulb?

Assembly only — bulb not included. You'll need to source a compatible HID bulb and ballast separately or transfer your existing setup.

Will I need new wiring or connectors?

This uses factory mounting points and electrical connections. Compatibility depends on whether your vehicle already has HID or you're upgrading from halogen — verify your harness type before ordering.

What if it doesn't fit perfectly after unboxing?

Test-fit immediately upon arrival. Housing alignment should be tight to factory tolerances — if gaps appear, don't force it. Contact support with photos before installation.
