Because the focal point is different from the original halogen bulbs, the light changes, resulting in shadows. Introduction to car headlights: Car headlights, also known as car front lights or car LED daytime running lights, serve as the eyes of the car. They not only relate to the external image of the car owner but are also closely linked to safe driving at night or under bad weather conditions. The role of light adjustment: It allows the car's lights to maintain an appropriate height at all times, facilitating nighttime driving and adapting to different road undulations. The importance of light adjustment: The more passengers in the back seats, the lower the rear of the car will sink, and the front of the car will correspondingly rise, causing the headlights to rise. This can dazzle oncoming drivers and distract their attention, easily leading to traffic accidents.

Having worked on cars for many years, I often encounter the issue of shadows from LED headlights, which is mostly due to the misalignment between the bulb's light-emitting point and the focal point of the original car's lens. Halogen bulbs have a fixed light-emitting position, but when replaced with LEDs, the light-emitting position shifts, causing the lens to block part of the light and create a shadow. Common causes include not inserting the bulb all the way during installation or poor bulb design. I usually recommend pulling the bulb out, rotating it to a different angle, and reinstalling it. Sometimes, adjusting it this way eliminates the shadow. If that doesn’t work, it’s best to switch to a specialized LED bulb designed for the lens. Avoid cheap, low-quality products. Shadows can interfere with visibility while driving at night, making it distracting and quite dangerous. It’s advisable to visit a trusted auto repair shop and have a technician adjust the position using a light meter to ensure the focal point is accurate before hitting the road.

Why is the car air conditioning compressor not turning?

Possible reasons for the car air conditioning compressor not turning include: 1. Insufficient refrigerant, which causes the computer to automatically stop the compressor. In this case, simply adding a certain amount of refrigerant can solve the problem. 2. It is also necessary to check whether the power supply and grounding of the air conditioning compressor are normal, whether the engine radiator and condenser are clean, whether the engine temperature is too high, and whether the air conditioning computer is working properly. These conditions can all cause the air conditioning compressor to stop working. 3. The primary reason for the compressor not working is prolonged use of the air conditioning system. Over time, severe internal wear can lead to the compressor failing.

Why is it necessary to warm up the car in winter?

Winter car warm-up is essential for engine maintenance. Due to the cold weather, the engine requires a warm-up period to gradually return to its optimal operating temperature, ensuring long-term durability. The normal operating temperature of a car engine typically ranges between 80°C and 90°C, with some high-performance engines reaching up to 100°C. After being parked overnight, the engine temperature drops to match the ambient temperature. The process of raising the engine temperature from ambient to its normal operating range is referred to as the cold start phase, which is precisely what 'warming up the car' entails.

What is the name of the protective panel above the car tire?

The panel above the tire is called a mudguard, primarily serving to block mud and dust. It is usually installed behind the four tires of a car, with the front two fixed on the left and right lower sills and the rear two fixed on the rear bumper. The entire mudguard consists of two layers: the outer hard layer is the wheel arch, commonly black, and the inner soft layer is the liner. The mudguard is composed of the wheel arch and the liner. Functions of the mudguard: 1. Prevent mud from splashing onto the car body or people, which can make them look unattractive. 2. While driving, it can block gravel and mud kicked up by the wheels. 3. Enhance the overall aesthetics of the car body. 4. Reduce the drag coefficient, making driving more stable.
