Honda Civic, Mazda CX-5 and other models with D4S HID ballast; OEM number 21571; located inside headlamp assembly; converts low voltage to high-voltage pulses to drive HID bulbs. New ballast ensures OEM electrical compatibility. Installation difficulty: medium; labor 30-45 minutes; remove headlight assembly and ensure high-voltage wiring insulation. If HID starts late, flickers, or one side fails while bulbs themselves test fine, ballast or internal circuitry likely failed and requires replacement.
