The Bulb Check: ​​​​​Rear Defroster Indicator Light

​​​​​​​​​​​​​​​​Whenever the light is illuminated, the rear defroster is turned on. This indicator isn't that common on regular vehicles but for SUV's, Mini-Vans and Full Size Vans, this indicator helps. It alerts the driver that they have the rear defroster on, even though most systems will turn off once the ignition is turned off.
