Generally, the convex mirror can be installed on the lower outer corner of the car's rearview mirror, or on the upper outer corner, with the mirror surface adjusted slightly downward. It is mainly used to see parking spaces and the ground when reversing, which is very useful and eliminates the need to constantly adjust the rearview mirror. Common installation positions include the upper left, lower left, and lower right corners. The difference between the upper left and lower left positions is not significant. Most people choose to install it on the lower left or lower right positions. Related introduction of the car convex mirror: 1. Function of the car convex mirror: The convex mirror allows the driver in the cabin to better observe the side of the car body and the rear wheels, expanding the driver's field of vision and reducing blind spots. The convex mirror is inexpensive and easy to install. 2. Installation on the lower left: Advantages: Increases the visible range of the rearview mirror. Disadvantages: It definitely blocks and interferes with the rearview mirror's line of sight. 3. Installation on the lower right: Advantages: It helps to see the distance between the rear wheel and the curb, which is very useful for roadside parking, driving on narrow country roads, and reversing. It hardly blocks or interferes with the rearview mirror's line of sight. Disadvantages: It cannot increase the visible range of the rearview mirror.

As someone who has been driving for over a decade, I always insist on installing the convex blind-spot mirrors at the lower outer corner of the side mirrors. This position provides a direct view of the rear wheel area, effectively reducing blind spots—especially useful during reversing or lane changes. I first clean the mirror surface thoroughly to remove dust and grease before firmly attaching it with the included adhesive. After testing, I found this placement offers clear visibility without obstructing the main mirror's rearview function. Positioning it too high or too inward can compromise overall rear visibility and lead to misjudgment. I recommend test-driving after installation to find the optimal angle—after all, different car models and driving habits vary greatly. This minor modification has saved me from numerous potential mirror-related accidents. Being low-cost yet highly practical, it's worth recommending to both novice and experienced drivers alike.

As a new driver who just got my license, I tried several positions when installing the blind spot mirror and finally found the outer lower corner to be the safest. Initially, I placed it at the inner upper corner, but it completely blocked my view of the blind spot and even interfered with the main mirror's display of road conditions—almost causing a problem while reversing. Now, with it positioned at the outer lower corner, it helps me easily see vehicles on the side, especially useful when turning or changing lanes on the highway. The installation process is simple: clean the corner of the main mirror with a damp cloth and press the small mirror firmly into place. Don’t forget to adjust your seating position to verify the field of view and ensure personal comfort. My driving instructor also taught this method, saying it could significantly boost driving confidence—and now I feel much less nervous while driving.

As a parent who frequently shuttles kids, the optimal position for the convex blind-spot mirror must be the lower outer corner without obstructing the view. That corner effectively covers blind spots, allowing direct observation of adjacent vehicles and reducing lane-change accident risks. Remember not to install it in the center or upper area—that would obscure the main mirror's view and increase danger instead. After installation, test its safety during driving: it provides extra reassurance when children get in/out of the car. This inexpensive gadget significantly enhances daily driving protection—install it sooner rather than later.
