Standlights flicker while flashing

Hello all, on our tour last week in the Harz I noticed the following: My 2 stand lights in the front flicker as soon as I turn left, right or turn on the warning flasher. More precisely: As soon as the flasher lights up, the stand lights become short weaker, then bright again, then weaker again, so exactly in counterclock to the turn signal. In the front the previous owner has 2 LED cover flashers and 2 LED tinted mini LED flashers installed. Since I have the turn signals in the front anyway austa The question now arises because of the described problem: do I just buy 2 LED turn signals for the front and leave it at the same time or do I convert it to halogen turn signals again? Can the flickering lie on the LEDs and no longer occur with the halogen turn signals? How difficult is the conversion? Does this work, or do I have to dismantle various panel parts before? Thank you very much for your help ! VG Mars
