KC 135 Belly Lights

[Wing_Z]

I'm hoping a Newshawks reader can come up with a description or better yet, a picture.
Through the fog of time I recall Jane's F-15E sorties where the hardest mission was to refuel on the way back.
As you approached the tanker from below, there were coloured lights which you used to guide you to the boom connect.
IS there a standard layout/colour for these?

Best I can do for now.

Many thanks Trans, I missed that one.
I'm trying to remember...I think those red and green lights are lensed or baffled.
As you approach, they become visible, bit like runway approach lighting.
