My truck has 'auto' for the lights.
At night front and back come on.
Depending on the spectrum of light during the day, the additional running lights will come on.
Nothin' fancy, just a newer Chevy Silverado.
It is actually automatically set on, 'auto' for the lights.
My friend has a Cadillac truck that is newer, that thing has traction control and will automatically deflate or inflate the tires depending on the situation. Whoa!
