Do these plug straight into my factory wiring harness?

Yes—these are designed as direct replacements. You pull out the old headlights and bolt these in. The factory connectors match, so no rewiring needed.

Will the halo stay bright if I run them as DRL all day?

LED halos are built for continuous duty. They run cool and draw minimal amperage, so brightness stays consistent through long days on the road.

What if one halo burns out—can I replace just that LED, or do I need a new headlight?

LED halo units are sealed assemblies. If a halo fails, the entire headlight assembly will need to be swapped. Individual LED replacement isn't an option on this design.
