What does the parking light of a car mean?

[McKhloe]

Parking lights are warning lights that serve as a safety reminder for the vehicle, pedestrians, and the surrounding environment when the car is temporarily parked and turned off, provided that the car is equipped with parking lights. They are used to indicate the position of the car. When the parking lights are turned on, the headlights will illuminate with a relatively low intensity, and the taillights will also light up, serving as a safety warning. Parking lights are applicable in the following situations: 1. When temporarily parked in dark environments, to prevent passing pedestrians, bicycles, and other traffic participants from colliding with the car. Turning on the parking lights can effectively provide safety warnings and outline the vehicle. 2. When temporarily parked and leaving on narrow provincial, county, or rural roads at night, the parking lights have a significant effect.

I found this feature particularly useful during a self-drive trip in Europe. When parking on narrow streets at night, you must turn on the parking lights because local regulations require the vehicle's outline to be visible when parked. Simply put, it's a small light on one side—for example, if you're parked on the right side, you turn on the left parking light so that oncoming cars can see there's a vehicle from afar. Nowadays, for cars in China with automatic light switches, you can activate it by flicking the turn signal lever toward the parking direction after turning off the engine. These lights consume much less power than headlights, protecting the battery and avoiding the embarrassment of finding your car dead in the morning.

Parking lights are designed to make your car noticeable to other drivers at night, as if the car is saying 'Hey, I'm parked here.' Traditional models require turning the key to power on the lights, but most new cars can activate them by holding the turn signal lever to the left or right for three seconds. Once, while helping a neighbor move his car, I noticed yellow lights on the left front and right rear. Upon asking, I learned this feature is called 'cornering lamps.' Beginners might confuse them with position lights, but position lights stay on when the ignition is on, while parking lights are specifically designed for parking safety.

Simply put, it's the one-sided parking light. Last time I drove my friend's Volkswagen Golf, I parked on an unlit roadside at night. After shifting to P gear, I pressed the turn signal lever downward, and the two yellow lights on the right side lit up. Some older Mercedes models are even cooler, featuring a dedicated rotary switch for the P gear position. This feature consumes only about 5 watts, so there's no worry about battery drain even if left on all night. It's especially recommended for use in unlit suburban areas, as it's more professional than using hazard lights. Note that some low-spec models in China may have this feature removed.

Mechanics who have disassembled car light circuits know that the parking light is actually a single-side operation mode of the width marker light. Once during a repair, I measured the current and found its power consumption is even lower than a phone charger. Nowadays, luxury cars have added more features - certain Audi models allow drivers to choose between illuminating both front/rear lights or only the tail lights via the central control settings. Personally, I find it most practical during heavy rain when temporarily parked - activating parking lights on foggy roadside provides clearer visibility than hazard lights without confusing following vehicles.

Those who have driven in Europe should be familiar with this: some countries mandate that parking on the roadside at night requires keeping parking lights on. The principle involves using the turn signal circuit but at a reduced brightness, so you'll see a single-sided yellow light glowing faintly. I've compared older and newer models: older BMWs require turning the key to the ACC position to activate it, while newer Mercedes-Benz models have a dedicated button on the door. It's advisable to turn them on immediately when stopping on the highway emergency lane during rain, as this, combined with a warning triangle, can triple the visibility distance. Be cautious not to leave them on for too long on flat ground, as the battery's capacity is limited.
