Why is the car door light not working?

[SavannahRose]

The reasons why the car door light does not illuminate when the door is opened may include the following: 1. Switch malfunction. 2. Blown fuse. 3. Short circuit in the wiring. 4. Some cars require the door light to be turned on near the sunroof/reading light before the door light will illuminate when the door is opened or closed. 5. The door and door switch are not making contact. Additional relevant information is as follows: 1. Based on the number of doors, car models can be classified into two-door, three-door, four-door, and five-door vehicles. 2. Considering the car's purpose and passenger convenience, the door opening angle is typically set around 70 degrees. 3. Car lights include headlights, taillights, turn signals, etc. Headlights further consist of high beams, low beams, front turn signals, and width indicators.
