What he said.

A "regular" flasher has a contact that bends when it heats up. When it turns on, it needs enough current flowing through it to heat it enough to cause it to bend. After it bends and turns off the lights, it cools and springs back to turn the lights on again. If the rest of the circuit (the signals themselves) don't use enough current to cause the flasher spring to heat up, then it remains on all the time.
