Why is the tail light of BYD S6 always on?

[PresleyRose]

The tail light of BYD S6 stays on because the brake light switch is damaged. Here is some extended information about brake lights: 1. Function of brake lights: Brake lights illuminate when the vehicle brakes, displaying red to warn following vehicles. Additionally, brake lights effectively prevent rear-end collisions and reduce traffic accidents. 2. Alerting following vehicles: Brake lights are bright and highly visible, primarily used to alert vehicles behind that the front vehicle is slowing down or stopping. Incorrect use or malfunction of brake lights can easily lead to rear-end collisions. 3. Precautions when replacing brake light bulbs: In China, vehicle tail lights are designed for 'dual-purpose' use, with bulbs containing two filaments - the dimmer one for parking lights and the brighter one for brake lights. Some manufacturers design them as high-low pin plug-ins for convenience. When replacing, be careful not to reverse the connections.
