The function of laser lights on highways is to alert and warn drivers. Here is relevant information: 1. Principle: These green lasers are anti-fatigue warning laser lights on highways, featuring high brightness and long range. They can effectively stimulate the brain of drivers who drive for long periods at night, using this method to prevent fatigue. 2. Function: The installation of anti-fatigue laser lights on highways can stimulate drivers through changes in light, thereby altering the visual fatigue caused by monotonous driving conditions. After multiple on-site inspections and concentrated discussions, highway traffic police have placed these laser lights on relatively straight sections of road that are prone to causing driver fatigue. The lasers are adjusted to ensure sufficient brightness while also providing a certain visual impact, effectively preventing driver fatigue.

What brand is KDS film?

Kangde Xin is the top domestic brand for car films and a member of the International Window Film Association, offering great value for money. Below are some important notes regarding film installation: 1. Do not roll down windows immediately after installation: Avoid rolling down windows for 3-7 days after installation. New car films are usually not applied to the edges of the windows, so do not open side windows or the sunroof after installation, as frequent window movement may cause the film to peel. 2. Avoid using suction cups or adhesive accessories right after installation: Do not attach suction cups, glue, or other accessories to the car film immediately after installation. Some films have brand logos, and owners may try to cover them with small decorations. Here’s a handy tip: use alcohol to wipe off these small logos. 3. Do not wash the car for at least three days after installation: It takes about a month for the moisture in the window film to evaporate completely. On sunny days, you can leave the car in the sun to speed up the drying process.

How Long Does Car Window Tinting Film Last?

The lifespan of car window tinting films varies depending on their grade: 1. Low-grade film: 1-3 years. Low-grade films are inexpensive but not suitable for long-term use. Over time, issues such as thermal insulation degradation, fading, wrinkling, and bubbling may occur. 2. Mid-grade film: Approximately 5 years. These films offer decent product quality and reliable after-sales service. 3. High-grade film: 5-10 years. Although more expensive, high-grade films perform well in terms of thermal insulation, clarity, and other properties. They feature specialized anti-corrosion and scratch-resistant coatings. Most premium films require high installation standards, as improper installation can easily damage the film or shorten its lifespan.

Does the fuel from private gas stations contain water?
