Does anyone have any advice or ideas?
I am having an issue in my car where the LED light I put in will glow very dim even when the car is off and there should be no power to it. The same thing is happening to the third brake light on the back of the car, it will glow very faintly when it's supposed to be off but work normal under full power.
I assume there is some sort of voltage leakage that is causing this to happen. I know diodes require just about 0.7 volts to conduct so I assume LEDs are the same way and there is at least 0.7v being supplied to them when they are "off".
I also know LEDs change their brightness with the change if current and so I was thinking a diode in series would drop the voltage enough to have the LED turn completely off.
