Feature: 1. Since the product is a convex mirror, it is normal to have some gaps at the edge of the rearview mirror after installing the convex mirror. When the convex mirror is pasted, the whole rearview mirror will become thicker. 2. The convex mirror is smaller than the al motorcycle rearview mirror lens, and the coverage rate of convex mirror covering the al rearview mirror lens is about 95%. It is normal that there is a gap at the edge of the rearview mirror, and the overall shape is consistent. 3. If the al rearview mirror lens of your motorcycle is cracked, but the lens does not fall off, you can directly paste the convex mirror on the al rearview mirror lens of your motorcycle, which is very convenient; If the lens of the al rear-view mirror of your motorcycle completely falls off and only the rear-view mirror shell is left (without lens), you cannot install convex mirror. 4 installation method: first, you need to wipe the al rearview mirror lens of your motorcycle, then you can tear a small part of the back glue at one corner of the convex mirror, and then you need to align the convex mirror with the al rearview mirror lens of your motorcycle. After alignment, you can tear off the remaining back glue. Paste it slowly from point to surface. Do not press the convex mirror lens vigorously after pasting to prevent crushing the convex mirror. You can view the installation video. 5.
