The main topic of the thesis is an example of a Printed Circuit Board for Center High Mounted Stop Lamp with Light emitting Diodes. At the beginning, I described the main characteristics of the LED and showed a few different examples of automotive lights with LED technology. In the following, I briefly described what the Printed Circuit Board is and what it is used for. Later, I also listed the guidelines and described the most general rules and some additional rules that are important for design of Printed Circuit Boards. Before describing the development of the PCB in detail, I also listed and described the most common types of materials used for Printed Circuit Boards, especially in Automotive Lighting. In the final part of the thesis, I described the development of a Printed Circuit Boards in three phases. In the first phase I presented the schematics, where all the necessary electronic elements were described and in the second phase I presented the entire construction of the Printed Circuit Board, where I put all the elements. In the third or last phase, the drawing process of two-layers PCB was described in detail, and in the end I showed the finished product, which was then sent to the serial car production.
