• The internal circuit board is fixed with glue injection to prevent damage to the internal electronic components and reduce vibration caused by looseness. At the same time, it protects the internal components from dust and rain in the environment and enhances safety.
• It starts quickly and can quickly reach full brightness without flickering at the moment the headlights are turned on, effectively improving visibility in front of the vehicle without waiting for a long time.
• The headlight control unit is an important part of the HID lighting system. It provides the voltage required to start the bulb and adjusts the voltage after the bulb is lit. A damaged ballast will cause the bulb to be unusable.
• To correctly diagnose a headlight failure, try moving the ballast from the working side to the non-working side. If the headlight starts working, replacing the ballast will solve the problem. If the problem persists, it may be that other components are causing the failure (most likely the bulb or line).
