As more manufacturers included brake lights in their cars, the market saw a necessity that was established by 11 states in America in 1928. It was now compulsory for all cars to have a warn light for brake.
This was a reply to higher volumes of tail-end crashes between vehicles in the nox or with low visibility. It would take several more years before brake lights become compulsory across the US. In 1974, the third brake light was a necessity in all cars in the US. As these were located higher, they were more visible to drivers behind, reducing the hazard of collisions flush further.

Cars built in the US before 2006 featured switches that immediately controlled the electrical power transmittance to the brake lights. modern cars, however, are much more different. today ’ randomness cars come with a computerize system named Controller Area Network ( CAN ) Bus system.
This system controls many of the car ’ second inner units angstrom well as exterior alight. It besides helps reduce the clutter of wiring throughout the vehicle while enhancing defect check and master of systems that operate through the ECU ( Engine Control Unit ). The CAN Bus system controls the brake lights besides. When you push the brake bicycle, it sends an encode signal to a control faculty. The lights receive power from these modules and illuminate. One major advantage of this system is that it ’ mho easy to detect a fail brake light light bulb.
