Is anyone aware of a way of modifying the original Hudson turnsignal switches so they could provide 4-way emergency flashers?
I know that aftermarket turnsignal switches with flashers are available, but they don't look right if you're trying for the authentic look of the original signals.
I envision the regular Hudson switch on the column, under the wheel, and then an unobtrusive flasher switch under the dash. There would have to be a "little black box" in the dash which isolated the left and right circuits. This would allow all four lights to blink on-off together with the flasher switch pulled, but then isolate them under normal circumstances so that the two left lights would blink together and the two right lights would blink together. And in models where the rear signals ran through the brakelight, there'd be a version of the black box for that type of light, too.
I ask this question because I know of a person who likes to devise custom electronics for old cars, and thought I might approach him about inventing the black box and offering it to us (and maybe other old car owners with similar 6-volt turnsignal circuitry). Of course, I'd also be interested in knowing if there is any demand for this sort of thing! I'm thinking that the price would have to be kept to less than $75, 'cause I'm a cheapskate.
But I need to know if there's something out there already. If there is, I don't want to trouble this guy!
