The Amber -Off (AO) Switchback bulb has special circuitry inside that senses when there is voltage on the (amber) turn signal circuit. Whenever there is voltage on the (amber) turn signal circuit, the bulb switches off power to the (white) running light circuit for 2 seconds. The result is that in most vehicles, the switch back bulb will flash amber-off-amber off whenever the turn signal is activated, even when there is power to the (white) running light circuit.
