Door jam switches can do this. You may have delay "off" lights so it could take some time. Put a coin where the button in the jam hits by tape - front doors first as they are used the most. If that helps either glue a dang penny in there or try to adjust the switch if adjustable. Go easy - don't twist up wires! The penny is safe and reversable!
