[928uk] Lights constantly on, please help!

[Dan Lepadatu]

Hi guys, 
Out with the 928 on this glorious day, turned the lights on in an underground parking, when turning them off they came down as they should but lights stayed on. Switched them on and off a few times but no luck. Finally disconnected the battery as we're late for the movies, anyone had similar issues?
Any help greatly appreciated.
Cheers,
Dan
