The cars become more futuristic everyday as well as they become more users
friendly. Extra features are added to help the driver with basic functions like
remembering to turn on/off headlights. It
is a modern convenience in many of today's cars. They eliminate the need for
the driver to manually switch the headlamps in certain driving situations. While
we have that function, the driver is still able to turn that off and control
the lamps himself. It is a handy option
because as it gets darker outside or even in the early mornings some people
just forget about the head lights for the visibility. With the automatic
function the driver doesn’t have to worry about that any more.
How
the Automatic Headlamps works?
The automatic headlamps are activated through a
photoelectric sensor which is embedded into the instrument panel. The sensor is
located at the base of the windshield under the defogger grill. The sensitivity
of the sensor is either set by the auto manufacturer or the driver. The sensor
is activated by the lighting conditions at dawn or dusk. The lights may switch
off up to five minutes after the engine has been turned off.

Switch Controls
As
I said before, the driver has the ability to turn off the functions of the
automatic headlamps by operating the light switch. If the driver turns off this
function and leaves the lights on, the car will notify you by a constant
beeping sound so that the driver can turn them off and avoid the battery to be
drained. [2]
