Beschreibung
Zusammenfassung:	The device e.g. headlight, has a ballast comprising an AC/DC converter with a high-voltage switching bridge. The bridge has four insulated gate bipolar transistor type power transistors with two transistors stacked on other two transistors. The transistors are installed on a substrate (SUB) of high temperature printed circuit type, capton type, ceramic type or lead frame type. A light source has a xenon discharge lamp and a high-voltage ignition module. Independent claims are also included for the following: (1) a lighting and/or signaling system comprising two lighting and/or signaling devices (2) a light source adapted to be mounted in a lighting and/or signaling device (3) a motor vehicle comprising a lighting and/or signaling device and a light source.
