With all kinds of references at my disposal I can't seem to find any pictures of (in color) an M4's tail lights. Now I know that the top half is red, is the bottom half red too? I can't find a good pic of this, any help will do.
TIA, Ken

I've got a superb color picture of one in the Squadron Signal Walk Around M4 Sherman (same on you not having one ) I'll send it to you later tonight. The upper "half-moon" is red, the lower rectangle is clear with a black bar set back and tiny red "cat eyes", just like the cat eyes on modern equipment but red instead of white. These would not be visible and best to paint gloss black.

That's the one book I do not own!!!! Rats, and yes, shame on me! Every store in town is sold out of that one...permanetly!!!!!!
Thanks Rob, kinda thought it was "cat-eyed", but had (shame) nothing to confirm it.
