It depends on your needs. Stick it on the upper left corner of the left rearview mirror: you can clearly see the rear wheel on your side; stick it on the lower left corner of the left rearview mirror: you may not see the rear wheel, but the field of view is wider; stick it on the lower left corner of the right rearview mirror: never install it on the upper right corner of the right rearview mirror, although you can see the right rear wheel, it will seriously affect your vision. Introduction to the small round mirror: The reversing small round mirror has adhesive on the back, so it is very easy to install. When installing, you can first confirm that it should be installed on the edge of the rearview mirror, otherwise it will seriously affect the field of view. Functions of the small round mirror: Reduce blind spots, it can eliminate the blind spot on the right rear side of the car body. Make reversing more convenient, you can also see the position of the rear wheels when reversing, making parking in reverse easier. Prevent scratches.

Having driven for over a decade, I can attest that choosing the right position for reverse parking mirrors can save a lot of hassle. My recommendation is to attach them at the outer lower edge of the traditional rearview mirror. This placement allows you to see the curbs near the rear wheels without obstructing the main mirror's normal field of view. Remember to clean the mirror surface thoroughly before installation, peel off the adhesive backing, align it properly, press firmly for 15 seconds, then adjust the small mirror angle with your fingers until the rear wheels appear centered in the mirror. Many people install them too far inward, which actually creates blind spots. This adjustment alone has helped me avoid wheel rim scrapes at least three times while backing in garages.

As someone who frequently parks in the city, I'm very particular about the placement of my reverse assist mirrors. I prefer to stick them on the outer lower third of both left and right side mirrors, which perfectly covers the blind spots near the rear wheels. When I first installed them, I tried several positions and found that if placed too high, I couldn't see ground obstacles, while too low made it hard to see the full side of the car. The current position makes navigating in and out of mechanical parking garages much easier and allows me to clearly see parking lines during parallel parking. Always check the mirror angles before driving, as vibrations can sometimes shift their position.

I think the best position for the backup auxiliary mirror is on the lower outer area of the side mirror. After adjusting it this way, when sitting in the driver's seat, the small mirror perfectly captures the position relationship between the rear wheel and the curb. During installation, keep your hand steady and slowly align it, then rotate the auxiliary mirror to focus on the area that needs the most monitoring. I drive my kids to and from school every day, where the school entrance is crowded with cars and people. This position helps me clearly see low obstacles behind while reversing. If the angle isn't adjusted properly, the reflection can be a bit glaring during the day, so this needs attention when adjusting.

I usually mount the reversing auxiliary mirror on the lower outer side of the rearview mirror. I chose this position because it doesn't obstruct the normal rearview angle while providing additional visibility of the rear wheel area. I remember one time when I didn't install it properly while parking, and I almost scraped against the flower bed near the corner. Now, I always confirm the position before peeling off the adhesive backing to ensure the small round mirror is mounted smoothly and securely. This position is particularly helpful for parallel parking, allowing me to clearly see the distance between the rear tires and the curb. During rainy days, water doesn't accumulate on the mirror surface, which is crucial for maintaining clear visibility.

Based on my driving experience, the optimal position for a blind spot mirror is just below the outer edge of the side mirror. First, clean the dust from the installation area, then clip the small mirror near the edge of the main mirror and press gently for 20 seconds to secure it. When positioned correctly, you can catch glimpses of the small mirror's reflection with your peripheral vision during turns. What I appreciate most is its ability to monitor blind spots near the tires that traditional mirrors can't cover, especially useful when reversing in narrow alleys. However, be careful not to place it too high, as this could distract you and compromise driving safety.
