Add a black based marker light.
It comes in two types, 3LED and 9LED, and comes in four colors: White, Orange, Red, and Blue.
You can choose position + blinker (L&R) for Orange and position + brake light for Red.
White can also be selected with only reverse lamps.
Blue is also available for daylights that light up with DRLs (electrics).
