The position lights of a car are located at the edges of the car's roof. Here is an introduction to car position lights: 1. Position lights are also called width lights, commonly known as small lights. 2. The function of position lights: Position lights are warning lights used to alert other vehicles. Literally, 'position' means warning, and 'light' refers to the outline, so position lights are warning lights used to alert other vehicles. 3. Position lights are generally installed at the edges of the car's roof, which can indicate both the height and width of the car. 4. There are two types of position light switches: rotary knob type and lever type. As shown in the figure above, the owner can find the gear to turn on the position lights according to the markings on the car. The lights that light up front and rear are the position lights.

I've been driving for almost twenty years, and those small lights around the car are called position lights. They help others see your car's outline in dim light, especially crucial at dusk or during rain. Typically located at the front, integrated into the side or bottom of the headlight assembly, like small LEDs; at the rear, they're within the taillight assembly, usually below the brake lights. The switch is mostly on the left stalk near the steering wheel—just twist it to turn them on. I remember once forgetting to turn them on and almost got rear-ended driving home late at night; now I habitually twist it as soon as I get in. Also, it varies by model: sedans usually have them fixed beside the headlights, while SUVs or off-road vehicles sometimes have them as separate small dots. Checking is simple—just walk around the parked car to see if they're lit. If one side isn't working, it might be a burnt bulb or wiring issue—just replace it promptly.

I'm a new car owner who just got my driver's license. My driving instructor taught me that the position lights (also called parking lights) are used to help others locate your car when it's not completely dark outside. They're not as glaring as headlights but make the vehicle more visible. On my Volkswagen, they're installed in small lamp recesses on both sides of the front bumper and near the license plate at the rear, integrated within the taillight assembly. The switch is straightforward—just a knob on the turn signal lever that you twist gently to turn them on. They're super convenient to use, and I turn them on every evening during my commute because they reduce accident risks, especially on highways where they help others see you. If you notice the lights aren't working, it might be due to loose wiring or a blown fuse. I recommend getting a multimeter to test or simply taking it to a repair shop for hassle-free troubleshooting.

From a vehicle design perspective, position lights are primarily distributed at the front and rear ends. At the front, they are often small LEDs embedded within the headlight assembly, while at the rear, they are integrated into the taillight structure, serving as safety warning lights to help other drivers identify the vehicle's position in low visibility conditions. Modern cars, like Tesla, have made them more stylish, using them directly as decorative light strips. The activation switch is typically located on the right-hand stalk of the steering wheel or controlled via the dashboard—just twist it to turn them on. In practical use, their activation should be determined by the environment: for example, automatically turning them on during cloudy weather is very useful to avoid accidental collisions. Regularly check if the lights are functioning properly by simply parking and observing their illumination status; if they fail, it might just be a bulb issue, which can be resolved with a simple replacement or professional maintenance.
