My 2005 G500 does not have any daytime running light (TFL). I have installed a retrofit solution that puts TFL on the current circuit of the stationary light. Works well. Problem: I always have to turn it on manually (i.e. light selector switch on position “Standlicht”, which undermines the safety idea of the TFL bitsl. I would like to convert it so that it is “always on” when switching on the ignition. How do I do this best? In the switch? In the wiring directly on the TFL (detonation gestures) I am grateful for any idea/proposal.
