Hi, in the doors of my A6 (probably also in the other Audi series) active spotlights are installed. They only light up when the door is open. There are 2 pieces per door, once in red as a kind of “backlight” and once in white to illuminate the floor. The attached image shows a red retro-reflector. Each W5W (5Watt) is as glass base variant. Since this is too dark for me, I wanted to retrofit LED and yet have found nothing bright. Most of them were darker than that the W5W. It is also important to note that the light has to be emitted at 90° angle! Now I have found this here and wanted to ask if someone already has experience with it (brightness, installation, …) ? http://www.benzenefabrik.de/en/article/9721/
