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.
1 In this dc circuit, the switch is closed (turned ON). 2  Voltage in the power sourceâthe âpotential differenceâ between the batteryâs two polesâis activated, creating pressure that forces electrons to flow as current out the batteryâs negative terminal.  Current reaches the light, causing it to glow.
