I'm assuming you've tried to activate the automatic light function again ? Turn them On/Off On/Off quickly until you hear it beep . Same procedure to deactivate them .
You might need the key in the ignition turned to the first position ( no engine running ) Some do , i don't on my 182 for some reason .
sorry to hijack.........
but onced turned on like you say... beep etc, they should stay on yes?
like evrytime you start the car, as sure mine are sort of resetting themselves.... back to normal?
tar
key in ignition, not engine running though,
turn on lights then off, then on then off!
then beep or beep beep...
