The installation position of the small round mirror on the rearview mirror: 1. For the right rearview mirror, install it at the lower right corner; 2. For the left rearview mirror, install it at the lower left corner, which provides a clear view of the left rear wheel position. The function of the small round mirror: It can reduce blind spots and prevent scraping accidents. The function of the car rearview mirror is to reflect the situation behind, beside, and below the car, expanding the driver's field of vision and reducing the occurrence of safety accidents. The adjustment method for the rearview mirror is: 1. For the left rearview mirror, place the horizontal line at the midline position of the mirror, then adjust the edge of the car body to occupy a quarter of the mirror image; 2. For the right rearview mirror, place the horizontal line at two-thirds of the mirror's position, then adjust the edge of the car body to occupy a quarter of the mirror image.

When I bought my first car, I was puzzled about where to place those small round mirrors. I initially stuck them right in the middle of the main mirror, which ended up blocking my view and falling off. After some trial and error, I finally figured it out. The most effective spot is usually the outer lower corner of the side mirror—for example, the bottom right corner of the right mirror. Place it near the edge but not too close, leaving some space to avoid getting scraped by tree branches or other obstacles. Before installation, clean the mirror surface with a damp cloth, then peel off the double-sided tape and press it firmly. Slowly adjust the angle to align it with the ground and wheel position, which helps eliminate blind spots when reversing and lets you see the curb clearly, preventing you from hitting it. If placed incorrectly, the mirror becomes useless and can even compromise driving safety. Getting the position right makes driving so much easier. Remember not to install it in the top-left corner or the center—I’ve helped friends install them a few times, and I always recommend the outer corner as the most reliable spot.

After years of driving, I've developed my own method for positioning small round mirrors—always placing them at the outer lower corner of the side mirrors. The bottom right corner of the right mirror is just perfect, sticking near the edge but not flush. This design maximizes blind spot coverage, allowing a clear view of wheels and road surface when parking to avoid scrapes. Installation is simple: clean the mirror surface, firmly attach the mirror, then adjust the angle to face the ground. Position selection matters—avoid the center of the main mirror or too close to the edge, as the former blocks vision and the latter is prone to damage from road debris, significantly reducing effectiveness. Once it becomes a habit, safety improves noticeably, making reversing much less stressful.

The small round mirror is most practical when installed at the lower corner of the outer rearview mirror, such as the bottom right corner of the right mirror, leaving some space when attaching it to the corner. First, clean the mirror surface to prevent it from falling off. After sticking it on, adjust the angle to see the ground and wheels. The key is to ensure it doesn't block the main field of vision. Correct positioning can eliminate blind spots and make reversing smoother.
