Do these mount to the factory headlight bucket without modification?

Yes — these are designed to bolt at factory mounting points with no drilling or bracket fabrication required. You'll be fastening to the existing holes on your truck's frame.

Will the sequential function work with my truck's stock wiring?

The headlights are built to integrate with your truck's OEM electrical connectors. The sequential pattern is controlled by the light module built into the assembly — no rewiring of the main harness needed. Consult your service manual if you have custom wiring installed.

Can I return these if they don't fit or work as expected?

ModSupply.com handles returns through standard policy — check your order confirmation for the return window and process. Keep packaging intact during the test fit to preserve your options.
