Will these bolt into my factory headlight buckets without modification?

Yes. These are designed for direct replacement at the factory mounting points. No drilling or bracket fabrication needed.

Do I need to reprogram anything after installation?

That depends on your truck's electrical setup and whether the OEM harness is plug-and-play compatible. Test the lights before hitting the road to confirm all functions work.

Are the sequential turn signals wired separately from the headlights?

The turn signals are integrated into the same assembly, but your truck's turn signal circuit needs to supply power to them. Check your factory wiring diagram to confirm compatibility with these units.
