Why doesn't the car interior light turn on when opening the door?

The cabin light is also called the interior dome light. If there are no issues with the car's electrical wiring, it's likely that the wrong button was pressed. Car usage instructions: In practice, specific analysis should be conducted according to different brands and models. For example, some vehicles require going to the instrument settings, finding the lighting settings, and then checking the box behind the welcome light. Therefore, how to operate it specifically should primarily refer to your car's user manual. Following the instructions in the manual is the most reliable approach. Door opening precautions: If the front passenger or rear passengers forcibly open the door against the driver's advice, causing a rear accident, the passengers bear the main responsibility. Slowly pull over to the side of the road, wait until the vehicle comes to a complete stop before opening the door, and stay focused when opening the door. The driver should remind passengers to open the door carefully. The driver should first check the interior rearview mirror to confirm if there are any pedestrians or approaching vehicles from behind, then look at the exterior rearview mirror to confirm side safety. Whether it's the driver or passengers, don't push the door open abruptly. First open a small gap to check the rear situation, and only open the door and exit after confirming it's safe.
I often drive, and it's common to encounter issues with door lights not working. Usually, it's either a burnt-out bulb or a fuse problem. Bulbs tend to age after a few years of use, especially in winter or rainy weather, making them more prone to failure. The fuse is located in the car's fuse box; you can test it by checking if another light works. A loose door switch can also cause the light to malfunction, such as when the contact point under the door handle fails. Additionally, short circuits or moisture in the wiring can be the culprit, which is more common in older vehicles. A non-functioning door light can be quite troublesome, especially at night when stepping over the door threshold can be dangerous. I recommend first checking the bulb or fuse yourself. If you can't fix it, take it to a repair shop promptly to avoid compromising safety. During routine maintenance, it's a good idea to have the technician check the condition of the small lights—it can save you a lot of hassle.
