Dome Light Dimmer is a smart circuit that adds several modern features to the basic dome light. It provides modern car functionality to the dome light by slowly dimming the light after 20 seconds when the door is closed and slowly increasing the light intensity when the door is opened. It monitors ignition and if ignition turned on the light fades as soon as the door is closed. If the door left open the light shuts off after 10 minutes of inactivity. Light also comes on when the ignition is switched off.

Dome Light Dimmer is universal and works with either Ground or Positive door switches. It is very small and easy to install. It provides up to 10 amp of current and will work with both LED and incandescent lights. It can be used with either a positive or sink light circuit making it truly universal.
