I've retro fitted some genuine CLK Xenon headlights to my 209. With just the ignition on all works fine, Had everything on to test. Turn the engine on (running) and the dipped beams both flicker and switch off. I have swapped the bulbs out with some spares I had and still exactly the same. if the lights are off and the engine is running, No flicker. Switch them on, they flicker and die. Same every time except maybe 2 or 3 attempts where they would stay alive for 30 seconds but still turn off in the end. Suggestions please, I really don't fancy taking the bumper off again. Oh I've also plugged an Autologic in and there's no option to add xenon in the lighting.
