Do these need any wiring modifications to work?

These are designed as bolt-in replacements. Your factory connectors will plug straight in — no cutting or splicing required for basic operation. Sequential halo function may require a separate controller depending on your vehicle's wiring; confirm compatibility before purchase if that feature is critical to your install.

What's the difference between halos and projectors?

Halos are the LED rings that glow around the headlight. Projectors are the lens and reflector inside that focus your main beam. This unit gives you both — the rings light up with that animated sequential effect, and the projector lens does the heavy lifting for road illumination.

Will these fit my car without modification?

These mount at factory headlight locations and are engineered for your model year. Installation is straightforward — pop out your old housings and slide these in. No cutting, drilling, or bracket fabrication needed.
