Doc here,

Check to be sure your not getting a reflection off something else..LED's will do that and look to be lit..

IF they actually are getting power from a source after shut down, Look for a Cap in line with the array, It may not be draining off right away, and holding the LED's on..If that's the case, you'll need a bleeder resistor to siphon off power after shutdown.

BRIAN:

Actually , an LED is a Diode..(Light Emitting Diode) If you counter oppose it with another diode you may end up with a "Crude" Gate..that you can't forward bias to turn it on..(that is a trial and error thing..)
