Methods to identify the quality of car window film: 1. Judge by transparency and color. High-quality films generally have high transparency, while inferior films often fail to meet transparency standards, making the view from inside to outside unclear after application. 2. Evaluate based on heat insulation performance, which is one of the key indicators for glass protective films. A simple test method can be used for comparison: place a piece of glass with the film attached over an iodine-tungsten lamp. If you can't feel any heat with your hand, it indicates a high-quality film. Car window film refers to a thin film applied to the front and rear windshields, side windows, and sunroof of a vehicle. This film is also known as solar film or heat insulation film.

What is the function of the L gear?

The function of the L gear is to limit the range of automatic gear shifting, increase torque, and output greater torque. Situations for using the L gear include: 1. When climbing a steep slope, you can choose the L gear, which will limit the vehicle to lower gears, preventing frequent gear shifts and making the vehicle more powerful when climbing, while also protecting the transmission; 2. When driving in snowy conditions, switching to the L gear can maintain the vehicle between 1st and 2nd gears, preventing excessive fuel consumption and vehicle wear. Generally, automatic transmission vehicles have six gear positions, from top to bottom: P, R, N, D, S, L. The commonly used automatic gear positions are Park (P), Reverse (R), Neutral (N), and Drive (D).
