Subaru Forester: Light control switch / Sensor for the auto on/off headlights

The sensor is as shown in the illustration.
CAUTION
If any object is placed on or near the
sensor, the sensor may not detect
the level of the ambient light correctly
and the auto on/off headlights
may not operate properly.
High beam
Low beam
When the headlights are on high beam, the
high beam indicator light on the
combination meter is also on...
Other information:
With the sun visor positioned over the side
window, you can use the sun visor extension
plate to prevent glare through the gap
between the sun visor and center pillar. To
use the extension plate, pull it toward the
rear of the vehicle. When you have
finished using it, stow it by pushing it
toward the front of the vehicle...
WARNING
Do not put any objects (including
straps or cords) over the steering
wheel pad, column cover, or
dashboard.
These objects could be entangled
with the steering
wheel, preventing the SRS
frontal airbag, etc. from operating
properly...
