This is a wild guess, but I'd try to make the thing out of clear plastic, paint some areas and put an LED right in the rear stub.
Ah, I wasn't referring to the exposed wires, but to the primer. It seriously looks good as a weathering effect.
There's a single 2mm lighthouse LED mounted in the center of the clear frosted dish. A length of fiber optic extends that light to the tip of the spire.
Well, it was a good thing, there are a lot of them around here, and I really like the Hood Looking forward to more. -Ricky
