This circut is very "tuned" , it may not be valid in the real world. Im just a beginner. The idea here is that when a break light goes out, you are notified by a handy indication light.. yellow. The relay is basicly tuned to the circuit, if you alter any component this wont work as intended. There are push buttons above each led to break the circut as if a bulb went out. The relay gains a smig of current and the relay turns off tripping the indicator ligh. Im sure with some more tweaking i can make the breka lights brighter. As i said im still new.
