1. The control panel is damaged: the high beam control panel is responsible for adjusting the brightness and color of the light source. If the control panel fails, the beam light will not be white when it is turned on.
2. Bulb problem: If the high beam is used for a long time or affected by vibration during transportation, the internal structure will be damaged or aged. Factors will affect the color and intensity of the emitted light, so that it is not white after turning on the machine. Need to replace a new model, specifications, good quality, performance matching LED light source.
3. Voltage problem: When the power supply system is abnormal (too low/too high), it will also interfere with the equipment to a certain extent, making the equipment unable to work normally and producing an error signal output. Check whether the power supply circuit is stable and ensure that the required power is provided within the correct range, so that similar failures can be avoided.
