Position lights are located at the high positions on the front and rear of the vehicle. The front position lights are next to the two headlights, while the rear position lights are usually integrated with the brake lights. Position lights are primarily used during driving in dusk, overcast, rainy, or foggy conditions to indicate the width and height of the vehicle, helping other drivers judge relative positions and vehicle size during encounters or overtaking. Typically, the color of position lights is white in the front and red in the rear. Functions of position lights: 1. They make the vehicle more easily identifiable during daytime driving; 2. When the vehicle is turning, the position lights are turned on to alert surrounding vehicles and pedestrians; 3. They provide road illumination during nighttime driving.

Last time a friend asked about this, I did some research. The position lights are located on the outermost part of the front and rear headlight assemblies. At the front, they are usually embedded in the corners of the headlight module, while at the rear, they are at both ends of the taillights. Some cars also have small yellow lights on the side wheel arches, which are also a type of position light. I always turn them on when driving in the rain or at dusk, as they help other vehicles see the outline and size of my car from a distance, especially when turning on overpasses—it's very practical. To locate them, you can start the car, have a passenger watch, and slowly turn the light stalk to the small light symbol position. around the car, and you'll see them all. If you really can't find them, checking the lighting diagram in the owner's manual or maintenance guide is the most reliable method.

Speaking of the position of the width indicator lights, I remember discussing it last time when helping my neighbor park the car. Basically, the design is quite similar for every vehicle: at the front, it's the light strip on the outermost edge of the headlight assembly, and at the rear, it's on the left and right ends of the taillight assembly. Like my SUV, it even has small light beads under the side mirrors. When driving, just pay attention to the dashboard—if you see a symmetrical bulb icon lit up, it means the lights are on. Once when I was driving on a mountain road in heavy fog, these lights allowed oncoming cars to spot me from over ten meters away, significantly boosting safety. If you're really unsure about their position, the quickest method is to find an empty spot at night, turn on the lights, get out of the car, and around to observe.

Back when I drove older cars, I always had to adjust the width indicator lights. Nowadays, the positioning is more obvious in new vehicles—the front width indicators are usually integrated along the inner edges of the headlight clusters, often designed as slender light strips. At the rear, they're embedded at the outermost sections of the taillights, with some sporty models even adding side markers on the rear bumper. Their practical function goes beyond just marking the vehicle's width; turning them on during rainy weather also helps pedestrians gauge the car's length. If you can't locate them, try activating the hazard lights and slowly cycling through the lighting modes—the illuminated small bulbs will reveal their location.

One night while picking someone up at the airport, I realized my rear position lights weren't working. These often-overlooked lights are actually crucial: the front ones hide near the radiator grille inside the headlight housing, while the rear ones sit right at the corners of the taillight clusters. My habit is to check if two parallel small amber lights are illuminated at the front. They become particularly noticeable in dim garages or during dusk driving, typically glowing in an amber color. For modified car enthusiasts, they might even install flowing strips on the wheel arches to enhance the position light function.

During the last , the technician taught me to identify all vehicle lights. The position lights are mainly distributed at four corners: the innermost edge of the headlight assembly has a separate bulb or light guide strip, and the two upper corners of the taillight assembly are permanent points. Some Chevrolet models even have auxiliary lights installed on the back of the side mirrors. It is recommended to develop the habit of automatically turning on the lights in the morning and evening during daily driving, especially in school zones to help children see the width of the vehicle. If you want to check the positions yourself, first power on the vehicle without starting the engine, rotate the light switch to the first position, and then get out to observe.
