AI Technical Summary
In traditional scooter control circuits, the daytime running light module and the nighttime running light module each occupy two I/O ports, resulting in insufficient I/O ports for the main controller and making it impossible to add new functions.
The daytime running lights and night lights share a single controllable switch. The switching unit is connected to the power supply, and the controller sends a light enable signal to control the opening and closing of the controllable switch, thus enabling the daytime running lights and night lights to share a single I/O port for control.
This reduces the number of I/O ports required for the scooter controller, lowers costs, and increases the scooter's functional expandability.
