My theory, thus far, had been that these red cones had been used on the second pilot version as saucer underside (and bow) position lights. Here's a rare shot
of the second pilot version underside with what appears
to be one of the cones fully lit (however, it's white, not red!).
I can't be of much assistance, other than my vague memory of the first Enterprise model I had around the early 1970s. I recall those two bulbs on the outer edges of the lower saucer section lit up. I can't recall if the bulbs were red or white. The subsequent model I had a few years later did not light up.
