Abstract
An emergency vehicle lighting system is disclosed having one or more emergency vehicle lights with a switch operable by movement of the emergency vehicle transmission shifter. An electronic circuit for disconnecting power to the emergency lights is provided when the emergency vehicle shifter is shifted into a park or neutral position. The circuit can comprise discrete components including a flip flop or a micro-processor circuit connected to the shifter switch to provide power to the emergency lights, and which has been programmed to cut off the lights when the switch indicates that the shifter has been placed in a park or neutral position.
