Why do the taillights stay on when the car is parked?

[VonEvangeline]

The reasons why the taillights stay on when the car is parked are: 1. The brake switch is faulty; 2. The car is not locked. The solutions for taillights staying on when the car is parked are: 1. Check if the brake switch is short-circuited and replace it if necessary; 2. Visit a 4S shop or a professional repair shop to seek help from professionals. Taillights are installed at the rear of the vehicle, with the main color being red, to enhance the penetration of the light source so that vehicles behind can spot the vehicle ahead under low visibility conditions, thereby preventing rear-end collisions. The replacement method for taillights is: 1. Use a cross screwdriver or socket to remove the bolts; 2. Pull the lamp assembly out from the rear pillar; 3. Turn the socket counterclockwise and remove it; 4. Remove the old bulb and insert a new one.
