Installation position of the small round mirror for car rearview mirrors: The left small round mirror should be installed at the upper left corner of the left mirror, and the right one at the lower left corner. Generally, car rearview mirrors have four corners, and the small round mirror for the left rearview mirror is best installed at the upper left corner. This not only provides a clear view of the rear wheels but also does not obstruct the rear view. Expanded knowledge about rearview mirrors is as follows: 1. Function: The rearview mirror is one of the important safety components of a motor vehicle's body, used to observe the rear road conditions during reversing and to monitor the surroundings while driving. 2. Materials: Currently, the reflective film of domestic vehicle rearview mirrors is generally made of silver and aluminum, with some using chromium. Abroad, chromium mirrors have replaced silver and aluminum mirrors in vehicle rearview mirrors. 3. Composition: The interior of the vehicle usually has an anti-glare rearview mirror, which consists of a special mirror, two photodiodes, and an electronic controller. The electronic controller receives signals of front and rear light from the photodiodes. If the light shines on the interior rearview mirror and the rear light is stronger than the front light, the electronic controller will output a voltage to the conductive layer. This voltage changes the color of the mirror's electrochromic layer; the higher the voltage, the darker the color. Thus, even if strong light shines on the rearview mirror, the light reflected to the driver's eyes by the anti-glare interior rearview mirror will appear dim and not dazzling.

The position of the convex mirror on the side mirror is crucial for reversing safety. From my experience, the ideal location is the inner lower corner of the exterior rearview mirror, slightly tilted toward the center of the vehicle. This placement allows the convex mirror to directly cover the ground blind spot near the rear wheels during reversing, reducing the risk of collisions. Before installation, I usually adjust the seat and steering wheel first to ensure a proper driving posture. Then, I start the vehicle and adjust the main rearview mirror for optimal visibility. Next, I temporarily place the convex mirror in the test position and move the car a few steps to check if the blind spot is effectively covered. If positioned incorrectly, the convex mirror may display unnecessary information, which can distract the driver. Additionally, in low-light conditions such as rain or nighttime, the mirror can be slightly adjusted inward to avoid glare. It's recommended to clean the mirror monthly to prevent dirt from affecting its effectiveness. Remember, safe driving is built on attention to small details.

I've installed small rearview mirrors several times myself, and I believe the optimal position is at the lower right or left corner of the main mirror, depending on which side of your car. Once properly adjusted, it provides a clear view of blind spots directly beneath the vehicle during reversing, such as rocks or small obstacles. I first use removable stickers to fix the position, then have a friend stand behind the car to help test and ensure the small mirror fully covers low-lying areas. If it's not accurate, repositioning is easy—don't rush it. If placed too high, you might miss objects; too low, and it could get dirty from splashes. For maintenance, choose a waterproof and anti-fog mirror material for durability, and wipe it regularly to maintain clarity. After all, this little helper makes reversing easier—get the position right, and it saves a lot of hassle.

The optimal position for the reversing mirror is at the inner bottom of the side mirror. Ensure it aligns with the rear wheel position during installation. It instantly displays blind spots near the wheels when reversing, helping to avoid obstacles. The adjustment steps are simple: sit in position, attach the small mirror to the estimated spot, and observe the view while moving the car. Common positioning errors include placing it too far to the side or too high, making it hard to see the actual ground. During rainy days, slightly tilt the small mirror to prevent rainwater from obstructing the view. Regular cleaning is also important, as dirt can blur the image. Safe driving requires attention to small details.
