Do these plug directly into my factory wiring harness?

Yes—they're designed as a direct swap using your truck's original connector and mounting points. No splicing or adapter harnesses needed.

Will these work with my truck's factory dimmer switch?

These integrate high and low beam function into one housing. Verify compatibility with your existing electrical system before installation, or have a tech do a quick test-fit to confirm.

What's the return window if they don't fit or work as expected?

Check our return policy at checkout or contact customer service with photos before install. Once mounted, fitment claims are harder to validate, so test-fit first if you have any doubts about clearance.
