What is the name of the light under the car door?
3 Answers
The light under the car door is called the fog light. Below is relevant information about fog lights: 1. Function: Fog lights are turned on in rainy or foggy weather, with strong light penetration to reduce adverse effects on driving visibility in complex weather conditions. The role of car fog lights is to illuminate the road and provide safety warnings during rainy or foggy weather, improving visibility for both the driver and surrounding traffic participants. 2. Operation position: Fog lights are generally set separately on a convenient part of the dashboard. In some small cars, turning on the fog lights can also activate the small lights, but the fog lights are not affected when the small lights are turned on.
I remember the first time I noticed the light under the car door, it was called a welcome light. On cars I've driven, like Mercedes-Benz and Toyota, that's what they call it. It's usually located at the bottom edge of the door, and it lights up when you open the door, mainly to illuminate the ground for easy entry and exit, preventing tripping or poor visibility at night. This little design is quite thoughtful, especially useful on rainy days or when parked in dark areas. If it stops working, it might be due to an aging bulb, poor circuit contact, or a blown fuse, and it needs to be fixed promptly. Some high-end cars even project the brand logo, adding a sense of personality, but the standard version is practical enough. Maintenance isn't too difficult—just wipe the dust off the light cover if you notice it, and replacing the bulb usually doesn't cost much.
When driving with my family, I often rely on the welcome lights under the car doors. These lights are very useful, illuminating the area around the feet to make getting in and out of the car safer, especially preventing the elderly or children from tripping. After evening gatherings in the park, they help us spot debris on the ground. They are called welcome lights, installed in a concealed yet efficient location. Common issues include burnt-out bulbs or malfunction due to damp wiring, which can be fixed by those with DIY skills—just turn off the power, remove the old light, and replace it with a new one. Don’t forget regular maintenance, like cleaning the lamp cover to prevent dirt from blocking the light. If you value this feature when choosing a car, consider the LED version for longer life and energy efficiency.
