What does the right brake light indicator on a Mercedes-Benz mean?
2 Answers
This is a prompt from Mercedes-Benz's light detection function, indicating that there may be poor contact or a damaged bulb in the right brake light. It is recommended to have it inspected. Reasons for bulb damage: The bulb damage warning light may come on due to weak connections in the wiring, which affects the resistance value of the lighting circuit, causing the vehicle's computer to mistakenly identify the bulb as faulty. Common vehicle lights include: Turn signals, brake lights, license plate lights, marker lights, front and rear fog lights, reverse lights, high beams, and low beams. If the bulb fault indicator lights up, it is recommended to immediately visit a 4S store or a professional auto repair shop to have a technician read the fault codes with a scanner to determine the exact issue.
The Mercedes dashboard displaying 'Brake Light Right' typically means the right-side brake light bulb is burnt out or has poor contact. I've been driving a Mercedes E-Class for five years and encountered this issue last year. At the time, I was worried it might be a brake system problem, but checking the manual revealed it was just a faulty taillight bulb. A friend helped replace it with a new H7 bulb—cheap and simple. Since then, I've made it a habit to check the lights every time I wash the car. Ignoring this warning could lead to rear-end collisions or fines since other drivers might not see your brakes at night. I recommend addressing it immediately by visiting a 4S shop or a specialized repair shop for a bulb replacement, which costs under 100 yuan—safety is no small matter. Having technicians inspect the lighting system during regular maintenance can help prevent such issues.
