Apparatus and circuit for operating a discharge lamp of a motor vehicle at two power levels
First Claim
1. An apparatus for operating at least one discharge lamp from an on-board voltage source of a motor vehicle, whereby the at least one discharge lamp has a gas-tight closed discharge vessel with ionizable filling and electrodes enclosed therein, and between these electrodes gas discharge is formed during operation, is characterized in that the at least one discharge lamp is operated for producing a taillight of the motor vehicle with a first, smaller electrical power and is operated wit a second, higher electrical power for producing a signal light.
