Your vehicle’s brake light is not working. What is the right course of action?

It's important that your brake lights function properly because they warn other drivers when you are slowing down or stopping. According to German traffic rules, if your brake light is not working, you should either have the vehicle repaired by a professional garage or, if you have the necessary knowledge and skills, try to identify and fix the issue yourself. Simply changing the brake fluid is not the correct solution unless that is actually the cause of the brake light failure, which is unlikely. Ensuring the brake lights work is crucial for safety and legal compliance.
