I used to own a '30 pickup that had been previously equipped with dual taillights and cowl lights. When I put turn signals in I used a SignalStat-based system using the stoplights and cowl lights and was very happy with it. I think the column-based lever is not only traditional but very intuitive. Have to say, though, that with the pickup's somewhat compressed cab and my not-25-anymore agility I often found myself hitting the turn signal lever upon exiting the cab.
My '31 Town Sedan came equipped with a turn signal set that the previous owner had installed (said he got it from "some guy advertising in the
Restorer"). It uses a box with switches and indicator lights that is magnetically attached to the left side of the cowl/fuel tank, similar to the current
Logo-lights system. It uses four amber LED lamps attached to the bumper clamps and mounted between the bumper rails. I don't like the separate control box on the cowl/fuel tank, and it bounces around and falls off on rough roads. One advantage is that this system has a buzzer when the turn signals are on, something that the SignalStat system doesn't (unless you add one during installation). A second advantage is that it's there! However, I think it's more intuitive to drivers in cars following to look for the turn signals in the tail lights, and I may try to convert the system to use the tail light bulbs rather than the separate bulbs (have to see if that will work with the control box, though).
I haven't yet decided what turn signal system I'll install when I get to building out the '30 Town Sedan, which is currently body off in restoration.
But Grumps, good on you, and good on your bride for prompting you to do it. I think turn signals are perhaps the single best safety upgrade that can be done for a Model A that is actually driven.
