I'm attempting to integrate a couple of LED pods into an automotive reverse lamp circuit. The problem being, while the vehicle is running there is a 8.5v current present on the reverse lamp power wire. Needless to say is that all LED pods and lights dimly illuminate while the 8.5v is present, so the LEDs are always powered on while the vehicle is running. When the vehicle is shifted into reverse, the voltage changes to 12 volts.
I am uncertain how to convert this line into a switched 12v output line for the LED pods....
