There was an EU rule about ten years ago that stipulated that rear lights are no longer mandatory in daylight. The reasoning being to save on fuel. Which is a ridiculous reason, even more so with today's LED lights.
I don't know about other EU countries but this was the reason that Sweden removed the requirement.
All cars in Sweden used to have the rear lights turned on at all time, even if the light switch was in the off position, but that changed around the same time.that stipulated that rear lights are no longer mandatory in daylight.
I don't believe these were ever mandatory in the EU? UK never had such requirement.
Edit:
What I mean is there are EU countries where lights are still mandatory and countries where it isn't so I cannot see how it could be linked to EU requirements either way.

I still think rear signaling could be improved dramatically by using a wide third-brake light to show the intensity of braking.
For example -- I have seen some aftermarket turn signals which are bars the width of the vehicle, and show a "moving" signal starting in the center and then progressing towards the outer edge of the vehicle.
So now take that idea for brake. When you barely have your foot on the brake pedal, it would light a couple lights in the center of your brake signal. Press a little harder and now it's lighting up 1/4 of the lights from the center towards the outside edge of the vehicle. And when you're pressing the brake pedal to the floor, all of the lights are lit up from the center to the outside edges of the vehicle. The harder you press on the pedal, the more lights are illuminated.
Now you have an immediate indication of just how hard the person in front of you is braking. With the normal on/off brake signals, you don't know what's happening until moments later as you determine how fast you are approaching that car. They could be casually slowing, or they could be locking up their wheels for an accident in front of them.
I see a lot of those on trucks here in the south. Good for when you are towing shit so people can see around all your junk in the trailer.

A lot of colorblind people can tell the difference between red-green and white.
They just percieve red-green as the same.
So they lose the visual cue for front-back under the proposed change.
Colorblind person here. If we're talking about limited visibility differentiation of front and back, the color of light is way less noticeable than whether we're looking at headlights or not (based on intensity). There would be no issue telling whether we're looking at a front brake light or a back brake light so long as the front brake light has headlights around it.

Reminded me of this Technology Connections video, in which the dude explained (among other brake-light related things) how some law allows electric vehicles to get away with not using their brake lights:
https://www.youtube.com/watch?v=U0YW7x9U5TQYeah my electric 208 is kinda like that (if I remember the video well, watched it a while ago) but since it's Europe there actually is a regulation about how much a car can decelerate before break lights come on, so instead of making the system turn the lights on they throttle how much it can decelerate for recharge and still makes you use the break to use full regen (and eventually the actual brakes, of course). So it's not a real "one pedal driving".

I think a secondary light that blinks quickly would be a good signal of emergency braking. Like some aftermarket motorcycle taillights that start with a blinking pattern before they stay on, but reverse the order.
So, standard brake light comes on at the standard time, at the first touch of the brake. For stronger braking, the second light comes on. For emergency braking, the standard brake light stays lit while the second light begins blinking frantically.
Edit for consistency
I think some cars also turn on the hazards automatically if you really hammer the breaks.

Anyone complaining about lane keep not letting them change lanes or make turns is telling on themselves
Okay Verstappen calm down there

Since we're all throwing random ideas out here, I want to equip my vehicle with an annoyingly loud external speaker so that when someone near me does something dumb, I can personally shame them.

I think that's a neat idea, but we could instead, collectively, just do better at following other cars at a safe distance. I know it's impractical to expect all drivers on the road everywhere to change their behavior, but it's also persistently frustrating as someone who has for years frequently been stuck in traffic to see 95% of drivers insist on following less than a car-length behind. Following too closely to enable decision-making or accommodate other drivers is the cause of like 98% of both traffic accidents and congestion, according to my completely anecdotal and made up research.
There's this idea I've been considering for a long time.
Imagine putting a remote controlled firework smoke bomb under the tailpipe, hidden from sight. At best a really stinky one that smells like burned rubber or something.
When someone follows to closely, just fake an engine issue or something by activating the smoke bomb and fill their AC air intake with the smell of burned rubber for weeks. Just to teach them to not follow too closely again.

If Japan introduced that they never caught on, unless it's specific to an area or model of car.
90% of the things that Japan introduced according to comment sections on the internet never happened (or never made it past the prototype stage) and the rest was actually introduced in Korea, not in Japan.
The Japanophilia is strong with a lot of people on the internet.

That could probably be implemented in most existing vehicles, and at least it would provide more information.

Japan introduced brake lights that increase intensity based on how hard the driver was braking. 20+ years ago. They tested it in the US and drivers found it to be “confusing.”
I suspect because there's no consistency in the brightness of vehicle lights. But that's one of the reasons why I think an incremental light bar would be better, there's no variation between vehicles. You could even make it more informative by flashing the whole bar when you first brake, so someone behind you can more easily see how much of the bar is being lit up.

I suspect a lot of that has to do with the entitled way people are driving these days. If you leave a car length gap, some kid will wrecklessly attempt to cram their way in because your lane momentarily moved slightly faster.

Does your state not require good lights on the trailers? I just built a new trailer last year, I was required to have full working brake and turn signals along with running lights, but I went the extra step and included more brake/turn lights on the front and rear of the fenders, along with reverse lights plus four marker lights along each side. Trailers are hard enough to see, I didn't want to make it harder for anyone by just sticking with the bare minimum.

Counterpoint: the dumb people could have them as well.

Every car needs proximity chat so traffic becomes like a COD lobby.

BMW has implemented this in the US market for the past 20 years or so at least. Under heavy braking, additional brake lights turn on. I believe they call that Brake Force Display. I’m sure they’re not the only manufacturer to do this, too
Plenty of cars flash their brake lights when ABS(/ESP?) engages, which is reasonable and should be a legal requirement IMO.
There's lots of room to give additional info in between that and "brake light is on because the driver doesn't understand that they can do mild adjustments by letting off the gas / stupid bitch-ass VW PHEV computer thinks using cruise control downhill with electric regen requires the motherfucking brake lights". It's like no-one realizes or cares that brake lights lose all purpose if they're on when the car isn't meaningfully decelerating. ARGH.

and honestly i have the same problem with that intended use. it often looks like a stopped car is attempting to turn out into traffic. IMO emergency lights should have a faster blink pattern or something to differentiate from turn signals.
There's a programmable flasher relay that does exactly this. It's specific to certain Toyota/Lexus and Subarus from the 2000s to mid-2010s, but it's something. I have one in my 2008 Sienna - the "emergency flasher" part is programmed to strobe, kinda like a tow truck. I like it.

probably because thats a terrible way to do it. It would be noticeable if a car started braking and then started braking much harder, but if they slam on the brakes you don't see anything change, just a normal brake light.

Seems much more complicated than having the brake lights rapidly flash during hard braking. But of course we couldn't do that in the US because our turn signals/hazard lights are red
