Ant-collision lights are green (left) and red (right). AC lights on top of a vertical fin can be white or red/white. Go here (can't attach a PDF, apparently) for a good explanation of full scale lighting requirements:

You can make the lenses from clear plastic and shape/sand/polish to final shape and tint with Rit dye or spray a light coat of translucent paint (RC car body paint works well). Or you could cast them from crystal clear resin with the right tint/dye added.
The formation lights are a lime green/bluish tone.

The red light is on the left and the green light is on the right. These are navigation lights, not anti collision beacons. Anti collision beacons always rotate or flash and are usually red or on some aircraft, amber. Tail lights are white. But save yourself a lot of trouble and get the Flugmodellbau product from Todd at Dreamworks.
