Got my AIM today -- thanks Frank! -- and the article on adding emergency flashers to pre-66 cars reminded me to write... I added emergency flashers to my '63 Classic in a really simple and somewhat kludgey way -- I wired a simple switch and flasher into the rear brake lights. Battery (fuse box) --> switch --> flasher --> brake light wire Obviously only flashes the brake lights, but I was mostly worried about getting rear-ended stalled on an urban freeway or something.
