Do these plug straight into the factory connectors?

Yes — these are designed as a direct swap into the OEM headlight housing. Use the factory harness connections; no additional wiring required.

Will the sequential halos work with my stock turn signal relay?

These headlights are engineered to sequence off the factory turn signal circuit. If you're running an aftermarket relay or custom wiring, test the halo animation before finalizing installation to confirm timing and polarity match.

What bulbs do I need, and are they included?

Bulb type and quantity depend on your specific vehicle's headlight configuration. Bulbs are not included — verify your current bulb specs before ordering replacements, as some LED or HID bulbs may require additional ballasts or wiring considerations.
