Is there a 'Ling' character on the back of the license plate?

Black license plates with a 'Ling' character are vehicles of foreign embassies and consulates, enjoying diplomatic immunity. Here is an introduction to license plates: 1. Classification: Ordinary vehicle plates (blue), agricultural and construction vehicles (yellow), urban special vehicles (green), military or police vehicles (white), foreign-related vehicles: embassies, consulates, and foreign enterprises (black). 2. Explanation: License plates, also known as vehicle registration plates, are plates mounted on the front and rear of a vehicle, typically made of aluminum, plastic, or stickers, displaying the vehicle's registration number, registration area, or other basic information. License plates serve as a unique identifier for each vehicle, allowing identification of the province, city, or county to which the vehicle belongs, and enabling traffic authorities to trace the vehicle's owner.
Honestly, many cars nowadays come with automatic headlights, and my own vehicle has this feature. Once activated, you don't need to worry about the switch—it uses a light sensor at the front to automatically detect darkness levels. If it gets dark, the headlights turn on, and they adjust just as sensitively when entering tunnels or during overcast/rainy days, making it super convenient. It significantly enhances safety, especially during dusk when drivers often forget to turn on their lights, helping prevent accidents. Some models even allow sensitivity adjustments to avoid false triggers, but a dirty sensor might cause issues, so it's best to wipe it clean during car washes. Overall, it's a practical little feature, and I'd recommend prioritizing this option when purchasing a car.
From a technical perspective, the working principle of automatic headlights mainly relies on the light sensor at the front of the vehicle to monitor changes in ambient brightness. When set to AUTO mode, the system compares the difference between interior and exterior light sources to determine whether the headlights need to be turned on. The core function is achieved through a computer chip processing signals for rapid response. This feature is particularly convenient and efficient for nighttime driving, eliminating the hassle of manual switching. However, sensor malfunctions, such as blockage by dust, may cause the headlights to operate abnormally, so regular maintenance is required to ensure reliability. When choosing a car, pay attention to the sensitivity differences among different brands.
