I'm looking at replacing the turn signal lights in my '83 300D with LED bulbs, but I'm wondering how to handle the whole hyper-flashing issue. I've been trying to find an electronic flasher unit for the car and had no luck at all, does anyone know of a source? Or is there even such a thing for a W123? In the end I could always settle for load resistors or maybe try CAN Bus bulbs, but I'd far, far rather replace the flasher if possible.

If anyone can help, I appreciate it in advance.
