I've have my lights on auto all the time, so this time of year they come straight onto dip with almost every ignition 'ON'
Plus 'walk in/out' lights means they come on when you unlock the doors, then go off when you open the door, then come back on again when you turn the ignition on. Then go off when you turn off the ignition, then come on again when you open the door, then go off again 30sec after you lock the doors.
Reliable? I hope so.
