Car blind spot mirrors can generally be installed on the lower outer corner of the car's side mirrors or the upper outer corner, with the mirror surface adjusted slightly downward. They are mainly useful for viewing parking spaces and the ground while reversing, eliminating the need to constantly adjust the rearview mirrors. 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 them on the lower left or lower right positions. Introduction to car blind spot mirrors: 1. Function of car blind spot mirrors: Blind spot mirrors allow the driver in the cabin to better observe the side of the vehicle and the rear wheels, expanding the driver's field of vision and reducing blind spots. These mirrors are inexpensive and very easy to install. 2. Installation on the lower left: Advantages: Increases the visible range of the rearview mirror. Disadvantages: It definitely obstructs and interferes with the rearview mirror's view. 3. Installation on the lower right: Advantages: Provides a clear view of the distance between the rear wheels and the curb, which is very useful for roadside parking, driving on narrow rural roads, and reversing. It hardly obstructs or interferes with the rearview mirror's view. Disadvantages: It does not increase the visible range of the rearview mirror.

I've been driving for half my life, and the position of the small round mirror directly affects driving safety. The ideal spot is the lower right corner of the driver's side rearview mirror. This position provides clear coverage of the wheels and rear blind spots, especially when reversing, allowing you to see the curb and tires clearly to avoid scratches. Before installation, remember to clean the mirror surface thoroughly and use strong adhesive to secure it firmly, preventing it from falling off in rain or on bumpy roads. I often advise beginners to adjust the angle to ensure it doesn't obstruct the main field of view, as that could cause more trouble. If you frequently drive on highways, placing it in the lower right corner helps spot vehicles from the side and rear more quickly, significantly reducing accident risks. Regularly check if the adhesive is aging, and maintaining a clear view is an essential driving skill—don’t just stick it anywhere for convenience.

As an average car owner, I find the small round mirrors most practical when stuck in the corner of the main mirror, like the bottom right corner for easiest use. This way, I can instantly see objects in blind spots when parking or changing lanes. When installing mine, I chose high-temperature adhesive to prevent summer heat from loosening it. Positioning it too high might interfere with normal viewing. Installation is simple with just three steps: clean the surface, find the right corner spot, and press firmly. While driving, test different angles until you can clearly see the wheels without being too far outward. If your rearview mirror has electric adjustment, ensure the small mirror doesn't block the buttons. With this placement, I've enjoyed significantly improved visibility for a whole year, especially seeing wheel positions clearly on rainy muddy roads.

From a technical perspective, the optimal position for blind spot mirrors is at the bottom corners of the side mirrors. Install them at the lower right corner for the driver's side and lower left for the passenger side - symmetrical placement works best. My installation tip: use a handheld mirror to assist. Temporarily fix the mirror first, then adjust the angle from the driver's seat to ensure complete blind spot coverage. I recommend using strong adhesive like 3M tape to prevent detachment at high speeds. Positioning too low may obstruct the main mirror view, while too high won't effectively eliminate blind spots. After adjustment, take a test drive to verify smooth lane-changing visibility. This setup helps judge distances and prevent scrapes - remember to clean them regularly for clear visibility.
