Automotive Lighting 63-11-7-440-879 Xenon Headlight Control Unit Ballast

The Automotive Lighting 63-11-7-440-879 is an OEM xenon headlight control unit designed to regulate and manage power delivery to high-intensity discharge (HID) headlight systems. This electronic ballast serves as the critical interface between the vehicle's electrical system and the xenon bulb, converting standard 12V battery power to the high-voltage output required to ignite and maintain the xenon arc.

Key Features:

• OEM-quality electronic ballast for xenon/HID headlight systems
• Precise voltage regulation ensures stable light output and extended bulb life
• Integrated safety features including overvoltage and short-circuit protection
• Weather-resistant housing designed for under-hood installation
• Direct replacement for failed or malfunctioning headlight control modules

This control unit is manufactured by Automotive Lighting, a leading tier-one supplier of OEM lighting components to European automotive manufacturers. When a xenon headlight control unit fails, symptoms typically include flickering headlights, delayed startup, or complete headlight failure. Replacement restores proper xenon headlight operation and light output.
