Universal car HUD display suitable for any type of vehicle, such as cars, trucks, SUVs, and RVs. The HUD (Head Up Display) technology projects driving data onto the front windshield, such as speed, water temperature, voltage, and trip distance. This display helps prevent the danger of drivers looking down at the dashboard, enhancing safety while driving. It features automatic and manual brightness adjustment, providing ease of reading the displayed data even during the day. The screen turns on and off with the vehicle's ignition, thus protecting the car battery and maintaining manual switch operation, making screen control easier.
