Car customization suggestions

Could you add police light bars for roof customization? 

Maybe add different colors with it like all blue, all red, or both colors. Also different style light bars. And not just for the roof, like real cop cars we can have scanners in the back or roof and lights all around the car. And a push bar for the front. Please Read This. I want this to be added! Oh and also police lights for inside the car front and back and also in the side windows. For the button we can turn on the lights by double clicking the button used for sounding the horn.
