How it Works:
The headlamp circut works because the electrons travel from the battery, through the resistors, powering the lights, and looping around from the third LED back to the battery. We chose to put the lights in parallel so that if only one light goes out, the current will not break. Another thing we used was a switch that can break the circuit. The resistor in the circuit keeps it from overloading the LEDs by weakening the current. By having the three LED's connected together, they serve as the wire for the circuit.
