With our reverse light program there's no need to flip an additional switch to activate backup lights when shifting into reverse. Since transmission gear state is automatically broadcast over CAN, we've decoded this message to automatically trigger a Kaizen Relay when you shift into reverse. All you need to do is upload this program to a Kaizen Relay, connect it to your vehicle's CANbus and connect the Kaizen Relay output to your light of choice!
