Gosh Jerry, you REALLY are older than dirt!

That kind of flasher makes the turn signal come on and stay on steady - not
flash- when a light at the other end of the car burns out. If the front
light burns out, the rear light won't blink because there isn't enough
current in the circuit to heat the bimetal parts inside the flasher.
