Do you know there is a feature called adaptive headlamps that allow you to see around a
corner or up a hill earlier whenever you're driving at night or in any low light conditions that would
cause you to use your headlamps.
A vehicle with adaptive headlamps will significantly reduce the possibility of a
collision as you will be able to detect hazards earlier. The reason why the term adaptive
is used is because the lights don't just turn to the left or right at a pre determined
angle. Sensors check the tire angle and the lights adapt to how much the vehicle is cornering
and the light is turned accordingly.
The adaptive headlight needs a variety of sensors to determine the steering angle, the
yaw rate and the speed of your vehicle to ascertain where the light
is needed the most. The direction of your is also monitored as well so the lights will not turn
in the direction of the steering while you're reversing.
Once the direction to point the light is located the lenses in the headlight can turn up to
30 degrees (up to 15 degrees to the left & right). The lights can also point up or down to adapt to
your vehicle when it is about to ascend or descend a hill, at the start of the hill the lights will
further up or down the hill and return to normal once the entire vehicle is now parallel with the
gradient of the hill.

Some vehicles have another method of adaptive lighting. A bulb is located at the corner of
the vehicle usually within the headlamp. This bulb remains off and is only activated in the same
manner via sensors when the vehicle is turning and turns off automatically when they are not needed.
I prefer the first type of adaptive headlamps because this method has one angle to direct the light, its
either on or off, with no rotation to adapt to different angles.
