🔴 Brake systems have an active role in development because they have become more effective and versatile. Brake systems in cars are considered one of the safest aspects that car companies innovate in their manufacturing, so that they can boast among other companies that they have a safer system in order to give reassurance to the consumer. The brake light sensor is a small part. It is an electrical switch that turns on the brake lights or tail lights in the car when you press the brake pedal, in order to alert the other cars that you will slow down so that a collision between cars does not occur. It is an integral part of the car's braking system, and some drivers drive their car without paying attention. The brake light sensor may be malfunctioning, or they may ignore its malfunction, but this is a very dangerous matter. Imagine that you are driving a car and you press the brakes but the taillights do not work or do not light up. This will lead to traffic accidents, and the car driver with a faulty brake light sensor is likely to be at fault. In addition, the brake light sensor has a direct effect on the anti-lock braking system, or ABS, the vehicle stability control system, or ESP, cruise control, and many other things. In today's episode, we will learn about the importance and working principle of the brake bulb sensor, what are the signs of its damage, and how to check and replace it.
