Rex:

That or hide 'em under a few German tin pots (helmets) like they used for lamp shades in quite a few or the WW2 movies (Patton in partiucular, for lighting his map-boards)

But if ya gotta choose... Tamiya ~does~ make a transparent yellow paint for lenses, as well as a red. Found that out a while back when working on my 4x4 Mountaineer (and his cousins) Then there is the simple idea of buying some colored overhead cels from an art store or even gift-wrap cellophane from the old stand-by, the dollar store!

And now that I think about it, any yellow overhead marker or highlighter should do for 'painting' the styrene. If ya got kids, try the markers first. Test it on a bit of sprue!

PS: And gently 'frosting' the inside of the lens helps diffuse the glow from a point to a full-lens glow. The Easy-Off/Mean-Green cleaners will frost the clear plastic... though a pit of coarse polishing compound on a Q-tip would do as good (if ya got any) In a pinch, Conet or any of those other 'grit' cleaning products do for a coarse polisher, and old toothpaste for a fine one (long as ya don't mind the lenses smelling minty-fresh! ;-) )
