Roof windows are not possible due to fire protection - what else?

That means window tape

That's exactly what I meant.

bla bla bla bla

Who shovels the snow off the roof at your place in winter so that meltwater cannot run in between the tiles once a certain height is reached?

A so-called gutter heating system provides a remedy here.

… but the OP probably doesn’t want to comment on the suggestions ;)

I love this slightly irritated atmosphere in this forum. I thank everyone for the comments, but they’re all leading in the wrong direction. Since the roof structure is already in place, a continuous strip of light is no longer (or only with great difficulty) feasible. The carpenter would have to take apart the entire roof structure again. I don’t want to interfere with the attic ceiling, so a higher placed window is also out of the question. Whether this type of construction is so special, I don’t know, and whether there will be problems with the gutter remains to be seen. When I drive through our town (15,000 inhabitants) or our district (80,000 inhabitants), I see such types of construction more than once. Anyway, thanks again for the information, the thread can be closed. P.S. One could, but only if one wants to, consider what the question was and what the answers were. I ask about artificial light that imitates a window, and instead of getting upset about the idea in the form of "You don’t do nonsense like that," "That’s not professional," or "Yes, you can do it, but it will never look like the real thing," one gets bombarded with the roof shape, the roof orientation, the designation of the construction method, and alternatives with real glass in the form of roof openings. I know this won’t please those involved here, and I’m the bad guy, but I couldn’t resist this comment now either.

Well, some answers are just indirect ;). Because one doesn't find the intended alternative so brilliant, one actually wants to know the original situation exactly, so that one can possibly reconsider alternatives for a real window.

I would like a window in the area marked in red, but according to BayBO that is not allowed - unless it is a fire protection window.

What speaks against a fire protection window? If I understand correctly, they mostly have fixed glazing. If it's only about light, that would be an option.

Nothing, and among the aforementioned options it will even be the cheapest. I just have to submit the plans again, but OK. I had also once googled for roof windows with fire protection, but it's not that easy to find.
