Should Rear Fog Lights Be Turned On When Driving at Night?

Rear fog lights should not be turned on when driving at night. Here is an introduction to fog lights: Fog Lights: As the name suggests, fog lights are designed to be used in foggy weather or conditions with low visibility. Since fog lights have a wide scattering range, they cannot focus the light, but they have strong penetrating power. When turned on, vehicles in front and behind can see each other from a greater distance in foggy conditions. Therefore, under normal circumstances, fog lights should not be used at night because their glare is as harmful as high beams and can easily annoy other drivers. Generally, low beams should be used for nighttime driving, and high beams can be used briefly on poorly lit roads to better see the road conditions.

Let me talk from the perspective of safe driving. Whether to turn on the rear fog lights at night depends on visibility conditions. Rear fog lights are extremely bright, and using them on an ordinary night without fog or rain can dazzle drivers behind you, even leading to rear-end collisions—how dangerous! Once on the highway, it was dark but visibility was good, and the car ahead had its fog lights on, making the rearview mirror glare so much I almost couldn’t see the road clearly. According to regulations, like China’s traffic laws, rear fog lights should only be used when visibility drops below 100 meters, such as in heavy fog, snowstorms, or heavy rain. On regular nights, low beams are bright enough—they protect you and respect others. Make it a habit: check the weather and road conditions before driving, and only use fog lights when truly necessary. This makes driving safer and avoids fines. Remember, safety first—it never hurts.

As an experienced driver, let me tell you. I hardly ever turn on the rear fog lights at night unless the fog is so thick I can't see. In the city with streetlights on, using rear fog lights seems unnecessary and even annoying. I remember last winter when driving to the suburbs at night, the fog was so heavy that even the front of the car was blurred, and the fog lights were a great help. But turning on fog lights on a clear night is like turning on a flash, disturbing the vision of drivers behind. My principle is: if I can see clearly 150 meters ahead, I just use the low beams, which is energy-saving and practical. New drivers should pay attention to this detail and not press the switch randomly. When driving normally, observe the environment more, use them when necessary, and save them when not needed. Keeping the road harmonious makes everyone happy.

As a new driver just learning to drive, I was also confused at first. I asked an experienced driver whether to turn on the rear fog lights at night, and he said they should only be used in foggy conditions—just use low beams for normal nighttime driving. Rear fog lights are too bright, and using them excessively can dazzle other drivers, increasing the risk of mistakes. Now when driving at night, I only use necessary light sources. If visibility is good, there's no need to add extra lights. The core of safe driving is not causing trouble for others.

What Causes the Throttle Control Function Failure in Volkswagen Santana?

Volkswagen Santana's throttle control function failure is largely caused by carbon buildup inside the throttle valve. The problematic throttle valve interior is typically coated with black carbon powder resulting from incomplete combustion. Prolonged use of the throttle and poor driving habits are also contributing factors to throttle failure. Throttle Introduction: The throttle is a controllable valve that regulates air intake into the engine. After entering the intake manifold, the air mixes with gasoline to form a combustible mixture, which then burns to generate power. Connected to the air filter above and the engine block below, it's often referred to as the throat of an automotive engine. Throttle Function: Throttle opening refers to the angle at which the engine's throttle valve opens. The vehicle's throttle is operated by the driver via the accelerator pedal to adjust engine air intake, thereby controlling engine operation. Different throttle openings indicate various engine operating conditions.

What are the symptoms of a faulty hall sensor in a tricycle motor?

Motor hall sensor failure can cause symptoms such as the motor not rotating, weak motor operation, or abnormal noises. Below is relevant information about motor hall sensors: Introduction: Generally refers to any machine that can convert mechanical energy into electrical energy or electrical energy into mechanical energy. Specifically refers to generators, electrical machines, and motors. Classification: By working power source - According to the different working power sources of motors, they can be divided into DC motors and AC motors. Among them, AC motors are further divided into single-phase motors and three-phase motors. By structure and working principle - Motors can be classified into DC motors, asynchronous motors, and synchronous motors according to their structure and working principle.

What is the number of the fuel pump relay for the Passat Lingyu?

The fuel pump relay for the Passat Lingyu is No. 372. Composition of the fuel pump relay: As a control device, the relay is connected in a circuit and requires two control systems—the input circuit (also known as the control system) and the output circuit (also known as the controlled system). Specific characteristics of the fuel pump relay: Generally, a relay has several main contacts, along with two coil contacts, resembling a contactor. The main contacts are connected to the controlled system, while the coil contacts are linked to the control system. However, the contacts of a relay are usually visible. Function of the fuel pump relay: The primary function of the fuel pump relay is to control a high-power circuit with a very small current, while also expanding the control range. When a signal reaches a certain value, it can switch, disconnect, or connect multiple circuits simultaneously based on the different forms of contact groups, achieving automatic switching. Another function is to adjust the opening and closing of the fuel pump as needed to ensure the normal operation of the engine.

How much does the Civic's fuel consumption increase when the air conditioning is on?

When the air conditioning is on, the Civic's fuel consumption increases by approximately 2 liters per 100 kilometers. Air conditioning fuel consumption: For a car that typically consumes 10 liters per 100 kilometers, turning on the air conditioning will increase fuel consumption by about 2 liters. The impact of air conditioning on fuel consumption is very noticeable, and different fan speeds also have varying effects. Principle of increased fuel consumption: The car's engine essentially powers the air conditioning compressor, so when the cooling air conditioning is turned on, the pressure on the car's engine increases, requiring more gasoline to burn for power. This is why sometimes when the cooling air conditioning is turned on while driving, the car's power feels slightly weaker—because the engine's pressure increases.
