What is a Position Lamp?
2 Answers
Position lamps, commonly known as small lights, are warning lights installed along the edges of a vehicle's roof to indicate its height and width. Their primary function is to alert other vehicles. Differences between position lamps on cars and trucks: Cars do not need to indicate height, as their front and rear position lights clearly display the height and width of the rear and the width of the front. Therefore, these position lights serve as position lamps. Trucks with a height exceeding 3 meters or a width over 2.1 meters must be equipped with contour lights, which are white at the front and red at the rear. This helps other vehicles determine relative positions and sizes during encounters or overtaking. Usage of position lamps: Position lamps should be turned on during dusk when drivers' visibility is weakest. Although the road may still be clear, vehicles at a distance become harder to see, making it essential to activate position lamps to alert others. Activating position lamps: Turn the light knob to the position lamp setting. When activated, the vehicle's dashboard will display the position lamp symbol, which consists of two 'D's with light beams on each side. In case of a breakdown or accident at night, both position lamps and rear position lights should be turned on to warn approaching vehicles and prevent secondary accidents.
As a regular driver who often drives home from night shifts, I deeply understand the importance of parking lights. I remember one time driving in foggy weather when I didn't turn on my parking lights, and the driver behind me almost rear-ended my car because they couldn't clearly see my vehicle's boundaries. Parking lights are essentially small lamps installed on both sides of the vehicle, typically at the front and rear positions, with red or amber colors. Their purpose is to display the overall outline of the car. During nighttime, rainy conditions, or low-visibility weather, they automatically or manually turn on to help other drivers judge the vehicle's size and position. Unlike high beams, parking lights have a softer brightness that doesn't glare, but they can prevent collisions in critical moments. I always remind myself to check if these small lights are working before driving, otherwise it's not only dangerous but could also result in a traffic ticket. There's also benefit to using parking lights in parking lots - they help pedestrians instantly recognize the vehicle's boundaries, reducing the risk of minor collisions. Simply put, parking lights are your car's safety indicator lights.
