The invention relates to a headlight (1) for motor vehicles, comprising at least one light source (2) which lies on a supply line (6) that can be switched to a power source (7) of the motor vehicle by means of a switch (8). The headlight is equipped with an internal electric energy storage unit (10) which is likewise connected to the supply line (6) and the at least one light source (2), and in the event of a drop/failure of the voltage (U) on the supply line, the light source is supplied by the internal electric energy storage unit (10) for a remaining lighting duration. In order to monitor the voltage (U) of the supply line (6), the headlight is equipped with a monitoring device (14) with a switch (14a) which is actuated by the monitoring device, wherein the monitoring device switches a signal line (15) that leads to a display means (16) for a user to the internal energy storage unit (10) in the event of a drop of the voltage on the supply line.
