Car small light is actually the position light, also called width light, which is a warning light generally installed on the edge of the car roof to indicate the width of the vehicle. The function of car small light is to remind other vehicles to pay attention when driving in the evening or at night, so that other vehicles can judge their relative positions and vehicle size when meeting or overtaking. When car small light needs to be turned on: Driving in foggy weather: Visibility is low in foggy weather, and the view is blurred. While turning on the fog light, the position light also needs to be turned on, which can play a good warning role and make it easier for other vehicles to identify. Rainy weather: The view is also blurred in rainy weather, and the car small light can be turned on alone for warning purposes. Driving in the evening: The road surface is still clear in the evening, but due to the lack of street lights, the front and rear vehicles start to become blurred. For safety, the car small light needs to be turned on to make it easier for other vehicles to see. Driving at night: Traffic regulations stipulate that the rear tail light and position light must be turned on when driving at night to alert the vehicles behind.

Through years of driving, I've deeply appreciated the importance of small lights, officially known as position lights or marker lights. Typically installed on both sides of the front and rear of the vehicle, they help outline the car's profile in low-light conditions such as night, dawn, or fog. Unlike headlights, small lights emit a soft glow that isn't too harsh, making it easier for other drivers to spot your position and avoid collisions. Operating them is simple—just turn the light switch near the steering wheel to the first position. I often remind myself to turn on the small lights when parking in the city or before entering tunnels—not only for safety but also to reduce the risk of fines. Regularly check the bulbs, as aging or burnout is common. You can easily replace them with a screwdriver—low cost and minimal time. Remember, road safety starts with these small details; small lights may be minor, but their role is significant.

Before every trip, I always check the lights. The small light, also known as the position lamp or marker light, is the small fixture that illuminates at the corners of the vehicle, typically indicating the outline of the car. It's mainly used to enhance the vehicle's visibility at night and is very convenient to operate—just a turn of the switch to light it up. I have personal experience with this; once in the rain, I forgot to turn on the small light and almost got hit by a car behind me. Since then, I've made it a habit to prioritize turning on the small light in low visibility conditions. It consumes very little power but effectively highlights the car against the background, reducing rear-end collisions. Its location is also easy to find, usually one near the bumper and another beside the taillight. If the small light doesn't work, it's most likely a bulb issue, and you can replace it yourself. Taking some time for maintenance is well worth it. Safe driving relies on these small details—don't overlook them.

The small light is actually the position light on the car, installed at the front left and right and the rear. I use it every day when driving, simply turning the light knob between the first and second gear to turn it on. It is mainly used at dusk or in foggy weather to make others see your car clearly, more low-key but effective than the headlights. When parking, I also turn on the small light to warn the cars behind and avoid accidents. In terms of maintenance, the bulb is easy to break, but replacing it only takes a few minutes. Developing good habits ensures safety.

As a car owner, I pay special attention to lighting maintenance. The small lights usually indicate the position lights, located on the front and rear sides of the vehicle. Turning them on enhances visibility in dark environments and reduces accident rates. Checking them is simple: see if the bulb is lit, and if not, buy a new bulb and replace it yourself. The location is easy to find, and all you need is a screwdriver to get it done in minutes. I test them during every maintenance check to ensure they remain functional. It's important to turn them on when parking or before driving at night to serve as a warning and avoid trouble. Though small, these lights can be lifesavers—don't overlook them.
