As part of the rules this year when the robot has decided which way to go at a traffic sign it needs to indicate this using indicator lights, early on i made the decision to add head lights, break lights, reverse lights and several other lights that are found on a car. Extra points are awarded for the look of the car so hopefully this will add to the overall appearance of the robot.
There are 7 different light circuits required and 3 inputs for the light switches, instead of tying up a whole port on one of the other PIC's I decided to use another PIC just for these features.
