Pros and cons of installing rain visors on rearview mirrors: 1. Advantages: Most rearview mirror rain visors are attached to the mirror cover using double-sided tape, serving to block rainwater. They are very suitable and effective during light to moderate rain. 2. Disadvantages: In heavy rain, the effectiveness of the rain visors diminishes, and the rearview mirror can still get wet. This improvement is more noticeable when it starts raining while driving. If it rains while the car is parked, stationary rain visors can accumulate many raindrops over time as rain continuously falls on them. It's necessary to wipe the rainwater off before driving.
Installing rearview mirror rain visors is actually quite practical, and I use them frequently. The benefit is that during heavy rain, they prevent water from hitting the mirrors, keeping the view clear. This means you don’t have to constantly worry about poor visibility of vehicles behind you, especially on highways or during rainy nights, making driving much safer. Installation is also simple—usually, you can just stick them on yourself, and the cost is only a few dozen yuan. However, the downside is increased wind noise, especially when driving above 80 km/h, with a noticeable buzzing sound near your ears. If the material is poor quality, they may degrade and fall off within half a year, requiring replacement. Additionally, they slightly increase wind resistance, leading to a minor impact on fuel efficiency. Overall, they’re recommended for rainy areas—just choose high-quality, anti-detachment models.
