Note 1: CEV 174 stick-on reflectors are also used on tail lights and turn signals. On a CEV 176 lens, the reflector number 174 is more prominant than the lens number 176. So most other people and places call the lens CEV 174.
Note 2: The generic 176 lens fits too tight on the mirror. The mirror edges must be filed.
