Material and durability The headlight control module is built with metal and ABS, flame retardant, and designed for good heat dissipation and vibration resistance. It helps the headlights operate more stably and ensures reliable ignition for both low and voltage levels. Function This HID xenon ballast converts voltage, stabilizes current, and protects against pulse surge to create a proper operating environment for the headlight. It supports longterm, efficient operation of the lighting system. Quick Start The ballast enables rapid lamp ignition by delivering a voltage peak to the lamp when it is powered. This voltage creates an arc between the lamp electrodes, allowing the HID bulb to ignite quickly and reliably. Compatibility and ordering note When placing an , ensure that the product page details and OEM specifications match your vehicle. If there is any discrepancy, contact relevant parties for verification. Practical use scenarios Replacing a faulty ballast in a HID headlight system to restore reliable ignition and stable operation. Installing or maintaining HID headlights to minimize startup delays and reduce voltagerelated flicker or instability. Routine headlight system maintenance on vehicles with HID lighting to protect against surges and extend component life.
