What is the Courtesy Light Bulb all about?

The courtesy light is meant to be a convenience feature that provides lighting inside your vehicle when it is dark outside. The courtesy light, or dome light assembly, is usually a plastic housing mounted in the headliner and contains one or more bulbs that can be illuminated by opening the door or by pressing a button or switch on the housing. The bulb inside has an electrical current that runs through it when the switch is in the ‘on’ position, which makes the filament inside the bulb glow white hot. Light is produced from this heat which illuminates the interior of your car. When the light bulb burns out, the filament has typically burned through at some point and can no longer transmit an electrical current through it to produce light. If the filament is damaged from heat but not burnt through, it might still glow but not a brightly as it used to.
