What Is A Courtesy Light Switch

Any time you turn on a light in your cabin, you can thank the courtesy light switch. It basically acts as a switch to complete the circuit and power light bulbs in your interior, including the dome light bulb and console bulb. When you enter your car, it makes sure the dome light turns on immediately to improve your visibility, and auto turns bulbs off in the case of certain cars. At night time, having this illumination can be especially useful. That’s why it’s imperative to be courteous to this switch.
