Do these lights plug into the factory wiring harness or require new wiring?

The switch and bezel suggest plug-and-play design, but exact integration method isn't detailed. Have your service manual handy during install to confirm connection points at the dash and headlight circuit.

Are the housings painted or raw plastic?

Housing finish isn't specified. Expect to inspect condition on arrival—they may need cleaning or light detailing before installation depending on storage.

What's your return window if these don't fit as expected?

Return and warranty terms aren't listed here. Contact ModSupply directly before ordering to confirm their return policy on lighting assemblies.
