With my 2014 Aero Plus 8 all the lights are off when the ignition is off, but when the door is opened and the footwel lights come on the main beam warning light, hazard flasher light and seatbeld warning lightd all come on, breifly. There is a clear "click" from a relay and then they go off. As it is a Plus 8 there is no boot..!!
So it soulds as if on your Aero a relay isn't working.
