I've been messing with car electronics for years, and this one still caught me off guard. While rewiring my classic Mustang, I tested the turn signals with only the dash indicator bulb hooked up. It lit up solid, and dim, and wouldn't blink. I bought a new flasher thinking I'd burned the old one out. Same thing. Turns out the old-school thermal flasher needs a minimum amp draw to cycle. With only one bulb on the circuit, it never heats up enough to click, so you get a dim, solid light. It's the same reason LED bulbs cause fast flashing or no flash at all with an original flasher. (A dim, solid bulb can also mean a bad ground or poor connection, so check those too before you buy parts.) The fix is an electronic flasher (it needs a ground wire). I swap one in, and the single test bulb instantly flashes bright and strong. I also picked one that still makes the audible click, so you don't drive around with your blinker on.
