After starting the car do you have to reach some set speed before they come on? I noticed when the car is started they don't come on, if you put it in Drive they don't come on, but when my wife backed out of the garage and started down the driveway they came on.
I know my 16 comes on as soon as you put it in Drive and goes off when you put it in Park.
