I got a neat NOS vintage turn signal. It's very vintage - no brake light switching. The cool thing about it is that it has a little nub that goes on the bottom of the wheel and makes it self-canceling. (I've tried the kind with rubber wheels for self canceling, and they slip.) The problem is that there are only two wires out of it - left and right - so it won't flash my brake lights. So how do I convert it? Some combination of relays / diodes perhaps? What I want is to end up with something that functions like this (animated gif) switch - but I need to do the brake-light-flashing part of it outside the switch. Any ideas? I thought I had it figured out while falling asleep last night but no, in the light of day my idea wouldn't work. Thanks HAMB!
