The HUD also includes five essential alarm functions to alert you to potential issues, promoting safer driving habits. Key Features 5 Alarm Functions: Includes Overspeed alarm, Voltage alarm, Water Temperature alarm, Fatigue Driving Reminder, and a general Fault alarm. Adaptive Brightness: A photosensitive element automatically adjusts the display brightness according to the ambient light, ensuring it is visible in bright sunlight and soft without glare at night.
