Lights control units

A vehicle control unit is an electronic module that controls and regulates various functions and processes of the engine and other technical systems of a vehicle. They were preceded by digital control units in electronic engine management systems, where they replaced the previous electromechanical ignition control. Later, they were also used for the electronic control of diesel engines. The increasing efficiency of electronic systems and the development of computer technology have allowed the development of control units with increasingly sophisticated functions. In addition, some new car models are equipped with more than 70 control units for various systems, such as special ESP (Electronic Stability Program) or ABS (Anti-lock Braking System) control units. In the process of operation, they receive the necessary data to control the various sensors. The control units visible to the driver are universal instruments with speedometer, tachometer and other devices. Safe driving is only possible if quality elements are chosen. One of these is the headlamp control units. Lights control units are needed to ensure the operation of the car lights.
