PCT No. PCT/EP94/00771 Sec. 371 Date Oct. 2, 1995 Sec. 102(e) Date Oct. 2, 1995 PCT Filed Mar. 12, 1994 PCT Pub. No. WO94/22700 PCT Pub. Date Oct. 13, 1994A circuit for triggering warning lamps including a self-conductive transistor circuit with a triggering circuit connected to the supply voltages. The triggering circuit keeps the transistor circuit blocked if the supply voltages are proper. If voltage fails, the transistors of the self-conductive transistor circuit open a current path from the warning lamp terminal to the control terminal of the power driver which results in switching on of the power driver and, thus, of the warning lamp.
