Installing a full-width tail light on a car is illegal. Tail light modifications must be registered and approved to be legal. Relevant Regulations: According to Article 16, Paragraph 1 of the Road Traffic Safety Law of the People's Republic of China, it is explicitly stated that no unit or individual may assemble a motor vehicle or alter the registered structure, construction, or characteristics of a motor vehicle without authorization. To modify a motor vehicle, changes must be made within the scope specified by the traffic management department, such as modifications to the body color, engine, fuel type, or chassis number. After submitting an application, the driver must obtain approval from the traffic management department before proceeding with any modifications. No unit or individual may assemble a motor vehicle or alter the registered structure, construction, or characteristics of a motor vehicle without authorization. Unauthorized modifications to the chassis, engine, suspension, transmission system, steering system, tire rims, lights, body color, or exterior structure of a motor vehicle without permission from the public security traffic management department, as well as any technical data of the motor vehicle that does not match the data announced by the competent department of motor vehicle products under the State Council, are considered modification acts.

Can Mainland Vehicles Cross the Hong Kong-Zhuhai-Macao Bridge?

Mainland vehicles require relevant permits to cross the Hong Kong-Zhuhai-Macao Bridge. Currently, apart from Hong Kong-registered single-plate vehicles, Guangdong-Hong Kong dual-plate vehicles, and Guangdong-Macao dual-plate vehicles, other mainland vehicles can only enter Hong Kong and Macao by applying for a one-time private car quota. Before the bridge opened, approximately 10,000 Hong Kong dual-plate private cars and 1,000 mainland private car quotas were issued. The following types of vehicles are allowed on the Hong Kong-Zhuhai-Macao Bridge: 1. Cross-border buses: In the first year of the bridge's operation, a total of 200 cross-border bus quotas were allocated, all of which have now been issued. There are also specific regulations for cross-border buses, which are not allowed to pick up new passengers within the bridge port area. 2. Shuttle buses: There are no quota restrictions for shuttle buses. The operating schedule for shuttle buses is as follows: during peak hours, they run every 5 minutes; during off-peak hours, every 10-15 minutes; and late at night, every 15-30 minutes. 3. Cross-border taxis: There are 250 cross-border taxi quotas for Hong Kong and Macao, with each quota allocated to one cross-border taxi. There are no restrictions on the number of trips for cross-border taxis. 4. Freight vehicles: In the early stages of the bridge's operation, Guangdong-Hong Kong cross-border trucks can pass through the Hong Kong-Zhuhai-Macao Bridge without formalities, and there are no specific restrictions on quotas.

What Are the Maintenance Methods for Car Batteries?

Maintenance methods for car batteries are as follows: 1. Turn off all lights before shutting down the engine: Some older models do not support automatic power-off after shutdown, so you need to manually turn off the headlights and interior reading lights before shutting down the engine. If you need to find something in the car or require lighting, you can use a mobile phone or flashlight for illumination, avoiding the situation where you forget to turn off the reading light, leading to battery power loss. 2. Turn off the air conditioning and audio system before shutting down the engine: The air conditioning system involves the compressor and blower, and the audio system is also a high-power electrical device. If not turned off before shutting down the engine, they will automatically start the next time the car is started, placing a heavy burden on the battery and causing damage. This is especially true for music enthusiasts who have modified their car's audio system, as the usual power consumption increases, and the impact on the battery during startup is even greater. Therefore, whether it's a temporary stop or a long-term parking, always turn off the air conditioning and audio system before shutting down the engine. 3. Avoid leaving the vehicle parked for long periods: The battery installed in the car will self-discharge during prolonged parking. Many car owners find it difficult to start the car or even find the battery completely dead after returning from a business trip or vacation. Therefore, it's best to drive the car at least once a week, with a trip duration of at least 20 minutes, to facilitate charging the battery while the vehicle is in motion. 4. Close the windows before shutting down the engine: The switches for the car's windows and sunroof are powered by the battery, so it's best to close all windows before shutting down the engine, rather than after shutting down or even using the long-press lock button method to close the windows after leaving the car.
