Nice Sunday, the brake light at the rear left (alcove construction) doesn’t work. 1. Light replaces, also tried at other places. It works, but not at the position of the left-back brake light. 2. It shouldn’t be a fuse either, because the brake light works at the right back. 3. I bent the contact pin already to the front, so that it is safe to contact. What else can this be? What would you do as a next step? In the appendix I have photos. Thank you, Alexander.
