Howdy everyone! I hope all is well where ever you are!
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. I purchased a couple of DC-to-DC buck converters thinking they may fix this problem, but I don't believe buck converters are the solution. I may be wrong but I don't know which item to use to produce a switched 12v on/off reverse lamp wire for the light pods. So I came here to ask about this.
I need something that ignores the 8.5v running current, and once a 12v current is present, it switches on the 12v power to the LED pods.
What do I use that will produce a switched 12v current when only a 12v current becomes present in the reverse lamp lead?
I also have an AC adapter for a Behringer audio mixer that is producing a total 21 volts. The mixer runs on 15 volts so I need to install a resistor; however, I'm uncertain which line to install the resistor. This overvoltage is producing feedback in the mixer's audio output. While I'm working on this mixer, I want to convert the connector to a different type because they don't make these type of AC adapters any longer.
