Amarnath S wrote: Smart lighting is more than 20 years old
In this country, we started building schools much more than 20 years ago, some of them with a build quality to make them stand even today! 
I am sure that the manufacturers would be jumping of joy if every new technology announcement would make every school, and other public institution immediately throw out all their old stuff and replace it with the new technology. (Sometimes, I have a feeling that it is that way!) I am not sure that taxpayers are equally happy with it.
I have been pondering 'smart' technology for my home for 30 years. Except for being 'new' and something to show to my friends, I still haven't found a single area where it has any other value for me personally. I guess that the situation is the same in many schools. If all you get from smart technology is dimmable light: We had that in my childhood, decades before the term 'smart home' was conceived.

I don't know about Norway, but I am pretty sure not having emergency lighting isolated to its own circuit from the main board is illegal here.

That surprised me, too. I can't believe that the solution at that school is according to Norwegian regulations. We use to be very strict on such things.
But then, if the school was built 50 years ago, and regulations were less strict then, maybe it was legal in those days. Maybe the politicians were so concerned about unnecessary public spending that when regulations were tightened, they decided to leave the school untouched.

I just looked up a 1976 copy of Australian Standard 3000 (Wiring Rules), which makes it clear that those provisions (separate circuit, protected wiring etc) applied then.
Maybe the school administration can expect a visit from the electrical authority.
As an aside, last year I had some wiring changes/additions in my house (new bathroom), and although the existing wiring is quite modern, they had to add an earth stake (MEN system) to comply with 2023 regulations.

You do point out that it doesn't get dark. Those signs aren't visible unless they're lit? In broad daylight?
Seriously, if the building has to be evacuated, they'll somehow figure it out. It's a classroom, I'm guessing the school isn't that big.
Warning labels were made for the people in charge. F****** nanny state is everywhere apparently.

Indoor signs do not always have 'broad daylight'. And even if it doesn't get pitch dark at night, indoor corridors do get a little shady when the sun sets.

There are reasons why that kind of signs have been introduced. I suspect that if your son or daughter were killed in a midnight fire when panic broke out because the sleepy crowd, just woken up, hadn't learned the layout of the school and didn't know the way out, you would have wished that there was a nanny there to help them out.
Sorry about being this cruel in my description, but in my eyes, you were the one starting out, referring to the requirement for a simple exit arrow as a 'nanny state'. The implications of what you are saying is that 'If they can't find the exit without an exit arrow, they deserve to die in that fire'. That is equally cruel.
Reserve the term 'nanny state' for more important things than mandatory exit signs.

...in a thread with a subject line of "sleeping in full light". Pardon me for somehow misinterpreting what "full light" means.

...and you choose to only bring this up now. I might have taken a different stance otherwise. You did kinda go out of your way in the original message to make a point about how it doesn't get dark.

Now you're trying to put words in my mouth, words saying the exact opposite of what I wrote, which is:
they'll somehow figure it out.
...IOW, I'm giving them the benefit of the doubt in that they're smart enough to find an exit on their own. But you tried to flip that around and infer I was saying they're not and deserve to die.
If that's not misrepresenting what I wrote (and intentionally trying to make me look like a complete jerk in the process), I don't know what is.

While the main breaker would kill ALL of the lights, code would not have allowed these two lighting systems to be on the same circuit, thus they would each have a separate breaker.

That is the crazy thing. I guess an electrician will be called to change the electric layout, now that this has come out.
I would even think that there was a requirement for a battery backup of the exit signs. There is a significant risk that what causes an evacuation also would cause the main power supply to be cut off.

So a bunch of kids, hyped up for a competitive sport on an exciting trip and probably with a lot of friends around.
Must be really well behaved kids if everyone expects them to drop off to sleep regardless of the light situation.
Not to mention of course that most kids can fall asleep leaning halfway out of a chair in a well lighted room with adults yelling right above their heads.

I actually have one, but he's busy.

I need to mount this to a bicycle and it's absolutely vexing me. Seems more difficult than it should be. If I had a 3d printer, I'd be sorted but instead I have cats.
I have a plastic container I'm going to cut up and velcro the to the bike. hopefully that works.

I have a cat and both FDM and SLA printers, and the coexist pretty well - the FDM is in a box, and the SLA is closed in anyway to keep sunlight UV out.
I'd offer to print the bit for you but the shipping cost and delay would make it unfeasible. Perhaps there is a member in the US who could do it for you? Or get one, they can be pretty fun (and the newer SLA resins are a pretty ABS like)

No, Dij is a black (with a little white) mass murderer and territorial assassin. He ignores them both, but used to attack the printer before I moved to laser.
He can however make phone calls, send emails, and write encrypted letters.

Random thought:
They make mobile phone holders for pushbikes.
Can you adapt one of them?

Maybe, but the real challenge is getting all the components together into a unit, rather than mounting the unit to the bmx.

I would need riding bifocals to use the trip computer I used in my 20s.

I'm already questioning the abilities of the bicyclists around here. This isn't helping.
I know this is generally not a popular opinion, but I've always wondered, I was about 7 when I realized a street is no place for a bicycle. Bumpers vs kneecaps type of thing, it seemed pretty simple in my 7-year old mind. What's their excuse?

I'd look for someone who could maybe 3d print an enclosure you could design yourself in some sort of CAD.
The key bit is probably just the loop they'd typically use for other things to attach to the frame and it's basically a clamp driven by a screw. The dimensions don't have to really be perfect, especially since you may not care so much if it stays perfectly oriented (like you would your brakes). You could use something like foam tape with a bit of give to fill the gap.
