Howard, lots of questions! Lets see what I can answer:
Here is a link to the Bosch site. They list a 6V unit. I think it has an internal blinker relay built into the switch that has a set blink timing and is not sensitive to a few watts +/- like the thermal blinkers we usually use in our cars. I don't know if the unit is ok for positive ground, but have a contact I can ask.
Bosch Classic Flasher Switch

The 12v one I installed (not in my car) was an incandescant bulb, and not LED.
54 should be BLS -Brake Light Switch

Note, the hand drawn diagram was from my car where I installed a double pole single throw switch and not the Bosch unit. The colorful computer generated diagram is for the bosch unit, but a picture I got of the internet someplace. Both units are pretty easy to splice into the existing wiring, and I think you can make all or most of the connections at the round connector on the steering column.

Edit: regarding 15 and 54 and 54f. 15 is just power that is switched on with ignition. and with 54 and 54f, you attach the output of the BLS to 54, and then 54f to the other side of where you broke the wire coming from your bls. It's been years since I installed this, I hope that makes sense.

Second Edit: I got feedback from a contact at Bosch Aftermarket, and even the 6V switch cannot be used with positive ground! Sorry, this is not an option for the golden anniversary.
