Have a look on ebay, at some of the vintage signal lamps that come up for sale. I like the look of some of the old ones that are a light-up arrows, with little visors on them. They do seem to be pricey though, as the rad rodder types like them too.
You can get re-pop signal stat type switches, but I don't care for them, as they don't seem to hold up as well as the old ones, but maybe I had a bad one. I had the seven wire model.
