vehicle behind at night, in order the user not to be dazzled by the light.
The front looking sensor detects brightness of the surroundings, while the
rearward looking sensor the strength of the reflecting light so that
adjusts the reflexibility of the mirror in the range of 7~85%. But, when
the reverse gear is engaged, it stops functioning.
