Headlamp Color

What is the little light bulb in the headlamp of the TC?

I just want to ask what is that little light bulb in the headlamp of the Scion TC? their actions, the ugly yellow light bulb ... so ugly .. I want to replace with a different color ... perhaps white, perhaps since the blue is illegal .. Does anyone know what is light? it is a parking lights? When I turn my light one knotch ... the ugly lights come on ... but when you turn twice ... the lighthouse is lit lowbeam ....

sounds like a light position, as is yellow. There is a reason that is yellow and I think it is a federal regulation that should stay yellow.
