Do these headlights bolt straight to my factory mounting points?

Yes — they mount at OEM attachment locations with no drilling or fabrication needed. You'll need a socket set and maybe 20 minutes per side. Unplug the factory connector, unbolt the old assembly, bolt these in, and plug in the new harness.

Are the sequential halos and projector lenses already wired and ready to go?

The LED halos and projector optics come pre-assembled and pre-wired into the housing. You connect the main harness to your vehicle's factory wiring. If your car runs stock turn signal bulbs, the sequential animation happens automatically on signal — no separate control module needed.

Will these work with my car's factory wiring, or do I need to run new harnesses?

They use your factory connector and wire gauge. If your vehicle's electrical system is stock and functioning, these headlights will integrate without additional wiring or relays. If you've heavily modified your electrical system or want to add a custom controller, test-fit first to confirm harness compatibility.
