If the small round mirror is stuck on the left rearview mirror, it is usually installed in the lower left corner because the left rearview mirror is generally used for reversing or overtaking. In China, parking is mostly done on the right side, so the left rearview mirror is rarely used during parking. Therefore, the position of the small round mirror for reversing should minimize the blind spot of the rearview mirror while also allowing visibility of the rear wheel. If stuck on the right rearview mirror, the small round mirror for reversing is typically installed in the lower left or lower right corner of the right rearview mirror. The lower left corner position provides a wider field of view for the rearview mirror, which is useful for overtaking and lane changing, while the lower right corner position helps gauge the distance between the wheel and the roadside during parking. The small round mirror serves to expand the field of view, reduce blind spots, and allow visibility of the rear wheel position when reversing.

When I first installed the blind spot mirrors, I was hesitant about the placement. After some trial and error, I found that sticking them to the outer edge of the lower left corner of the left side mirror works best. Specifically, it's the outer edge of the mirror's lower left corner, which provides a clear view of the tires and curbs during parking and reversing, helping to avoid scraping the rims. Before sticking them on, I cleaned the mirror surface with a damp cloth to remove dust and grease, then pressed gently to minimize bubbles. After driving a few times, I fine-tuned the angle to cover the blind spot, which significantly improved visibility during lane changes and enhanced safety. For new drivers, I recommend not placing them too high or in the middle to avoid obstructing the main view, and remember to check periodically for any looseness.

Having driven for decades, I've gained considerable insight into the optimal placement of blind spot mirrors—typically affixed to the lower right outer corner. This positioning provides flawless blind spot coverage, particularly when turning or parking by allowing visibility of the rear wheels, significantly reducing scraping risks. During installation, choose the smooth edge of the primary rearview mirror for a stable, vibration-free fit, and avoid using sharp objects to clean the surface to prevent scratches. While driving, adjust the angle to suit personal preferences, as improper placement can create additional hazards. Always ensure it doesn't compromise overall rear monitoring.

Choosing the right position for the small round mirror is crucial. I believe the best spots are the lower right or lower left corners of the main rearview mirror, towards the outer edge. Installing it expands the blind spot visibility, making parallel parking much easier. The process is simple: clean the mirror surface and stick it firmly in place. Avoid placing it in the center or upper part of the mirror to prevent obstructing your view. After driving, test its effectiveness and adjust the angle if necessary. Selecting the right spot before installation saves time and hassle.
