HID Xenon Headlight Ballast Control Module Car Ballast for Volvo 31297941 Xenon HID Headlight Ballast Control Unit
Product Description:
Xenon HID Headlight Ballast Control Unit
OE numbers: 31297941
Applicable vehicle type: For Volvo
A car xenon lamp ballast (also known as an HID ballast) is the 'ignition controller' of the xenon headlight system. It is responsible for instantly boosting the vehicle's 12V voltage to over 23,000V to ignite the xenon arc, and then stabilizing the output to an 85V AC square wave to ensure the bulb operates at high brightness continuously.
Installation and selection key points:
- Match bulb models such as D1S/D2S/D3S/D4S/H7/9005... Different bases require dedicated interfaces;
- Space measurement: Ultra-thin type ≤ 13 mm suitable for motorcycles and Japanese cold glue lamp shells; Split high-voltage boxes can be external;
- Decoding requirements: For European and American cars (Volkswagen, Ford, Jeep), 'CAN-bus decoding' must be selected, otherwise, the dashboard will alarm;
- Wiring harness upgrade: For 55W scheme, simultaneously replace with 10A fuse and 2.5mm² power wire to avoid heating of the original 1.5mm² wire;
- Reliable grounding: The ballast shell and vehicle body should have ≤0.1Ω grounding to prevent high-voltage pulse interference with the vehicle network.
