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.
Fluorescent lamps also flicker as they are turned on because it takes a few moments for the gasses to heat up sufficiently to produce light. LED lights do flicker, but not in the same way, and as a matter of fact, they flicker at such a fast rate of speed that it is usually imperceptible to the human eye.
