Will this need any wiring or does it plug straight in?

These are direct replacements that use OEM connector and mounting. Wiring compatibility is standard for the vehicle platform — your existing harness plugs directly into the assembly.

Is the bulb included or do I need to source one separately?

Bulb is not included with the assembly. You'll need to transfer your existing bulb or source a compatible replacement that matches the OEM spec for your vehicle.

Can I install this myself with basic hand tools?

Yes. Removal and installation are straightforward — typically involves removing the old unit, disconnecting the connector, and bolting the new assembly in place. Use basic socket and screwdriver tools. Your service manual will have the exact torque specs if needed.
