What are the waterproof and breathable products for car headlights?

There are many waterproof and breathable products for car headlights. Currently, some of the better domestic brands include Dongguan PUWEI and Shanghai PUW. Advantages of waterproof and breathable products for car headlights: Automotive waterproof and breathable products can reduce condensation in headlights, block most contaminants, and maintain long-lasting brightness. Headlights are constantly exposed to various weather conditions, road conditions, and environments that may affect vehicle performance. Splashing water, humidity, automotive oil, road debris, and dust can all degrade headlight performance, affecting both appearance and safety. Rapid temperature drops can cause internal pressure to decrease, drawing in contaminants, increasing fogging, and potentially leading to headlight failure. Using PUW waterproof and breathable membranes for car headlights provides benefits such as preventing water fog, balancing pressure differences, preventing pressure buildup, dustproofing, and oil resistance. Extended industrial applications of car headlight waterproof and breathable products: These products can also be applied to car headlights, electric toothbrushes, electric hair clippers, electric shavers, mobile phones, car wiper motors, LED outdoor lighting, and more.

What is the definition of the 4 wires in a reverse camera?

DC power plug connects to the reverse light, generally only the red wire is connected, along with the red wire on the RCA plug, providing the signal for reverse video switching to the head unit. The RCA connector transmits the video signal from the camera to the head unit. Below are detailed introductions about reverse cameras: 1. Selection of reverse cameras: (1) For passenger cars, consider the camera model (optional waterproof and night vision features), screen size (3, 5, or 7 inches), and power supply voltage (12V). For large vehicles like trucks and buses, 24V is sufficient. (2) For large vehicles, selection should be more cautious. The operating conditions of large vehicles differ significantly from passenger cars. For example: harsh driving environments on construction sites, extreme temperatures, high frequency of reverse gear usage, and long working hours. Large vehicles typically use a 24V power supply, so reverse cameras designed for passenger cars cannot be used. Therefore, when selecting a product, ensure it is the right fit rather than being influenced by price or other factors. 2. Considerations: When choosing a reverse camera, ensure compatibility with your vehicle model by evaluating the camera model, power supply voltage, screen size, waterproofing, shock resistance, and anti-interference capabilities.

Is Yunliang Modification Legal?

Yunliang modification is legal. In 2016, Yunliang showcased four legally modified vehicles at a modification car exhibition, where the 'legalization' of automotive custom modifications became a hot topic. The four legally modified vehicles displayed by Yunliang at the exhibition—Justice, Tundra, Pickup Version Wrangler, and Savannah—attracted significant attention from attendees and became the highlight models of the event. Below is an introduction to car modifications: 1. Body Modification: This includes changing the car's color or adding decorative elements to the exterior or interior, enhancing the aesthetic appeal of the car's surface or interior. 2. Performance Modification: Performance modifications involve the car's braking system, suspension system, intake system, etc. Braking system modifications may include installing high-performance, high-temperature-resistant brake pads or larger brake discs. Suspension system modifications can involve replacing shock absorbers or reinforcing the suspension structure, with shock absorber replacement being the most popular choice among car owners. Additionally, modifying the car's air filter can improve the rate of air exchange.

Can the S gear be used at a speed of 120 km/h?

When driving on the highway without the need for strong acceleration, you can choose to use the D gear for normal driving. If you need to accelerate quickly or overtake, you can directly shift to the S gear and then shift back to the D gear after completing the overtaking. Additional information: 1. D gear: It can be called the "Drive gear" or "Forward gear." When in D gear, the driver only needs to control the speed by managing the throttle and brakes. 2. S gear: S stands for Sport, which translates to "sport" in Chinese, meaning more powerful performance. 3. Situations for using the S gear: Generally, the S gear is used for overtaking and climbing hills, where the vehicle's performance will be more effortless and precise. Long-term use of the S gear will noticeably increase fuel consumption, so when driving on the highway and needing to overtake, you can shift to the S gear. The best choice when going downhill is to shift to the S gear, especially on long and steep descents. Using the S gear downhill allows the engine to assist in braking, avoiding potential brake failure caused by continuous braking.

What brand is the original tire of FAW-Volkswagen Jetta?

FAW-Volkswagen Jetta's original tire is the Hankook OPTIMO-K415 series tire, which is a tire that balances performance and comfort with a relatively long lifespan. The specifications are 185/60R15 or 175/70R14, indicating a focus on fuel economy from the size perspective. More relevant information is as follows: 1. Automotive tires can be divided into pneumatic tires and solid tires based on the structure of the tire body. The vast majority of modern vehicles use pneumatic tires. Depending on the internal air pressure, pneumatic tires can be categorized into high-pressure tires, low-pressure tires, and ultra-low-pressure tires. Low-pressure tires are commonly used in various types of vehicles. Pneumatic tires can also be divided into tube tires and tubeless tires based on their composition structure. Passenger cars generally use tubeless tires. Depending on the arrangement of the internal cord ply and buffer layer, tires can also be classified into radial tires and bias tires. Radial tires are commonly used in vehicles and are marked on the tire sidewall. 2. Some tires are designed to combine the advantages of different types of tread patterns. For example, some tires designed for urban SUVs combine block tread patterns with central rib patterns, which not only improves the tire's handling and straight-line stability but also enhances its grip and self-cleaning capabilities.
