Yes it does. There is not a car made for this country where the headlights would automatically turn on without turning on the taillights. It's federal law. The headlight bulbs might illuminate without the taillights turning on because of DRLs, but if you turn on the headlights or have the switch set to auto, the taillights will come on. Some manufacturers might add additional features like headlights (and therefore the taillights) come on when the wipers are on, but the auto switch, if it turns on the headlights, will also turn on the taillights. If it doesn't, then it's not controlling the headlights, it's controlling something else.
