The interior light in a motor vehicle is one of the more useful aids to a driver and passengers. Its operation is simple yet extremely effective, ensuring that whenever one of the doors of the vehicle is opened, the interior light is activated, enabling the interior of the car and its contents to be clearly visible in even the darkest of conditions.
In most vehicles the interior light is positioned within the vehicle immediately above the dashboard or around the ceiling. In some larger models of car there is more than one interior light to ensure that light is shed around the whole of the vehicle’s interior. The interior light unit connects to the vehicle’s battery independent of the ignition system, enabling it to be engaged at any time that one of the doors is opened.
Some interior lights are capable of being tilted in order to cast light on a specific spot within the vehicle. There are generally three basic controls that are available for the use of a standard interior light. The usual mode enables the light to switch one when one of the vehicle doors is opened and to switch off (sometimes with a short delay period) when the door is closed. Alternative settings are permanently on and permanently off.
The interior light serves as a useful aid to drivers and passengers in all vehicles during the hours of darkness.
