on my car it is the same,i thought that is how they work,undernieth the headlight buckets there is a switch about 2 inches long,when the head lights come up they push in that swtch,this the activates the light,it lets you know if your driveing in the daylight and your buckets come up,at least thats what i thought,my light comes on every time the buckets are up whether the lights are on or off.if i am wrong let us know.
