The method involves using a lamp with a gastight closed discharge vessel with an ionisable filling and electrodes inside between which a gas discharge is formed. The lamp are operated to create a tail lamp with a first, minimal electrical power and a signalling lamp with a second, higher electrical power. Preferably, the second, higher power is at least twice the size as the first minimal power. The signalling lamp is a stop lamp. The ionisable filling of the lamp contains neon. The lamps are fed by a medium frequency supply voltage and an operating parameter is controlled by pulse width modulation. |
