Question needs more information such as, does lights stay on on one side, or both, front and rear, does it flash, does it stay on even when you don't single.
When this happens, wiggle the turn signal stalk. If this fixes the problem, you need a new turn signal switch. Sometimes when you hit the brakes, the lights will come on. This is an indication of a bad switch.
Check your turn signal stalk switch. In some cars, German ones in particular, this is an intentional safety feature. If the turn signal is not centered the parking lights stay on so it is more easily seen at night if the car is parked on the side of a narrow street.
