Does this mount at the factory location without drilling?

Yes, this uses factory mounting points — no drilling required. Bolt it in where the original sits.

Will I need to splice wires or run new electrical?

Mounting method and electrical configuration are not detailed in the product specs — verify the connector type and wiring before purchase to confirm whether it's a direct plug-and-play swap or requires modification.

Does this come with a bulb or LEDs?

The assembly includes integrated LEDs — no separate bulb to install or replace.
