I need to develop an LED fog light for a specific car. It needs to fit inside the original fog light housing. The internals of the headlight would be replaced with the LED matrix. The functions should include white light fog lights. Turn indicators. Emergency hazard lights. Day time running lights. I have a photo of the prototype someone has created in the past, and I am very happy with their result. I want to achieve something similar. I need to work out how to control the light, how much power and which driver to use, and design a PCB with LED's on it.
