The position lights of a car are located at the highest points of the front and rear of the vehicle. The front position lights are situated beside the two headlights, while the rear position lights are usually integrated with the brake lights. Position lights are primarily used to indicate the width and height of the car during driving in conditions such as dusk, cloudy days, rain, or fog, helping other vehicles to judge their relative positions and size during encounters or overtaking. Typically, the front position lights are white, and the rear ones are red. Commonly known as small lights, position lights serve as warning lights to alert other vehicles. They help display the width and length of the vehicle at night and inform following vehicles about the size and width of the vehicle ahead during rainy or foggy conditions.

As a frequent driver, I've noticed many people asking about the location of the width indicator lights. They are positioned at both the front and rear ends of the vehicle: at the front, they're situated on the outer corners of the headlight assembly, such as the left or right edge of the headlight cluster; at the rear, they're located along the edges of the taillight assembly, typically adjacent to the brake lights. Width indicator lights primarily serve to enhance visibility in low-light conditions, helping other vehicles discern your car's width, such as when they automatically activate during nighttime, rain, or fog. I recall an instance on the highway during heavy fog when they prevented a potential accident. Designs vary across different vehicle models: sedans tend to have more compact placements, SUVs may position them higher, while luxury cars sometimes integrate more conspicuous LED lights. Safety is paramount, so I've developed a habit of checking them: after starting the car, I turn on only the electrical light switch and verify their illumination from the side. The bulbs are prone to burning out, especially with aging wiring, necessitating quarterly inspection and replacement. While their location isn't complicated, neglecting them could pose risks, as they assist in navigation during parking or turning maneuvers.

When I first started driving, I also couldn't figure out the position of the width indicator lights. They are the side lights located at both ends of the car: the front ones are on the outer edge of the headlight assembly, and the rear ones are near the sides of the taillight cluster. Their purpose is to illuminate when there's insufficient light, allowing others to see the vehicle's dimensions and avoid collisions. As a beginner, I learned that they are particularly important when reversing or parking, especially in dark urban garages. Now, I manually check them by pressing the interior light button or using an app to simulate turning them on. Their position is simple, but in some newer models, they are integrated into the daytime running lights for a more modern look. I recommend new drivers read the manual or watch online videos to confirm the position diagram. In terms of safety, they reduce the risk of accidents, and the bulbs are cheap and take only minutes to replace. For maintenance, avoid dust buildup to ensure clear visibility. In short, their position is fixed and easy to find, and developing a habit of checking them boosts driving confidence.

Having repaired cars for many years, I'm very familiar with the position of the side marker lights: they are fixed on the outer corners of the front headlight assembly and the rear taillight assembly. Their function is to indicate the width of the vehicle under low light conditions, making it easier for other vehicles to identify. Common issues include bulb burnout or wiring short circuits, and their location is often overlooked. Inspection method: observe the illumination after turning on the light switch. Maintenance recommendation: regularly clean the lamp cover to prevent dust from affecting visibility.
