Does this headlight come with the HID bulb and ballast?

The assembly includes the housing and reflector. Confirm whether the bulb and ballast are pre-installed or need to be transferred from your original headlight before ordering.

Will this work with my stock electrical connections?

This is engineered as a direct replacement for factory HID systems. If your vehicle originally came with HID, all connections align. If you're upgrading from halogen, additional ballast and wiring modifications will be necessary.

What do I need to do to prepare the headlight before installation?

No prep work is required before install. Once you remove the old assembly and disconnect the electrical connector, bolt this one in place and reconnect. Test beam output before final assembly.
