Shop our range of HB4 9006 xenon HID replacement bulbs for existing aftermarket HID conversion kits.
Each bulb includes its attached wiring and is designed to operate with a compatible aftermarket retrofit xenon HID ballast. These are replacement bulbs, not a complete conversion kit, and will not operate directly from the vehicle’s standard halogen connection without a compatible xenon HID ballast.
