Will these bolt straight to my factory headlight mounting points?

Yes. They're designed for factory mounting points — no drilling, no custom brackets. Jack up the vehicle, remove the old units, and bolt these in place.

Do I need to rewire anything for the LED DRL to work?

The LED strips are self-contained within the housing. Wiring specifics aren't detailed in the specs, so confirm compatibility with your vehicle's electrical system before final install — your local shop can test-fit and verify connections in 15 minutes.

Are these a complete bolt-on replacement, or do I need to keep my factory reflector cups?

These are complete headlight assemblies. You're swapping the entire unit — no reusing factory internals. Old housings come off, new ones go on at the factory mounting tabs.
