En smart og nyttig konstruktion for bilisten. Lyset i kabinen slukkes ikke, når døren lukkes. Der går en kort tid, hvor nøglen kan sættes i tændingslåsen o.s.v., før lyset automatisk forsvinder. Forsinkelsen er justerbar.
A clever and useful circuit for the driver. When you enter the car and the doors are closed it keeps the interior lights on for a few seconds to give you time to put the key in the lock, fasten your seat-belt and start the car. Stop fumbling in the dark! The same delay is introduced when you leave the car giving you time to check the alarm system and see if you have forgotten something. The delay is adjustable. The circuit has been designed to work off the car battery (12VDC) and is small enough to fit anywhere in the car.
