LIGHT OPERATION
When the lights are switched to position I (Low), the current runs through the light switch, through the diode
which reduces the voltage to the lights. The lights will operate in a low-light condition.
When the lights are switched to position II (High), the current runs through the light switch and directly to the
lights. The lights will operate at full power.
