Re: LED's glow when off most likely it is circuit leakage of the light itself. A fraction of a milliamp can cause an LED to glow but not put out useable light and the amount of energy used over a year is probably just a few pennies so I wouldn't put a lot of effort in trying to fix it if that is the issue.
30 and 87 create the switch to your lights. By default this switch is open, so the current cannot get from the battery to your lights. 30 â is your power source for your light. It connects to the positive (+) side of your battery or to a switched power source that only gets power when your ignition is on.87 â goes to the positive side of your LED lights.85 and 86 use electrical current to create a magnetic force, which then closes the 30 to 87 switch and allows the electricity to flow to your lights. Without this current, no magnetic force is created, so the 30 to 87 switch stays open, and your lights stay off.7 â goes to the positive side of your LED lights. 85 and 86 use electrical current to create a magnetic force, which then closes the 30 to 87 switch and allows the electricity to flow to your lights.
