Why do the brake lights stay on without pressing the brake pedal?

[VonColeman]

Since the rear lights of a car are used for width indication at night, they must remain constantly illuminated. Below is relevant information about brake lights: 1. Car rear brake lights: Rear lights refer to white lights installed as close as possible to the rear of the vehicle, displaying uninterrupted illumination. From directly behind the vehicle to 67.5° on each side, they emit a horizontal light arc of 135°. Their visibility distance is required to be 3 and 2 nautical miles based on the length of the vessel. They are used to indicate the vessel's movement and identify the movement of other vessels, aiding in determining crossing or overtaking situations. 2. The function of car brake lights: The purpose of rear brake lights and high-mounted brake lights is to make it easier for vehicles behind to notice when the vehicle ahead is braking, thereby helping to prevent rear-end collisions. The brake indicator light on the dashboard serves to alert the driver when the rear brake lights are activated.
