I know how flow lights work. But they still don't help you see better that a car is turning away from you, which is what this discussion is about.
Imagine a crossroad where a car is coming from your right side. You have no way of knowing whether they turn right or go straight, regardless of the way the lights work, because you won't see them.
If you're looking at the side of the car, you don't see them the same way as from the front. Which this whole discussion is about.
If you can see both turn signals from your point of view, current design works well enough.
Because this is what the discussion is about?
Personally I just want front turn signals to be visible from the opposite side again.
That doesn't answer the question. The question is how you would design it so you can look at the left side of a car, know that it's turning right and isn't prone to misunderstandings.
How would that work? On the highway, a slight nudge on a straight means you'll cross a lane, meaning turn signals on.
A kilometer later, the exact same slight nudge could mean it's just a light turn in the road, meaning signals off.
Now you could mandate cameras in all vehicles, which analyze your driving and turn on the turn signals when it thinks you're making a turn. Now who's responsible in a false positive if someone else dodges you and crashes because you suddenly turned on the signals without turning? Except it wasn't you, but your car. Oh and also you made entry level cars 10k more expensive, making them way more inaccessible if you aren't rich.
It's not that easy I think (and you had by far the best idea in this thread now).
Can't make them red or orange, they'd be just turn signals.
Can't make them green, that wouldn't work for color blind people, and since you actually need the color for understanding what signal you get (unlike traffic lights) you actually have to make it work
And arguably you can't really make them white, because you can't see a white blinking light inside a headlight and couldn't differentiate it from the back light. Same with light blue.
Which leaves darker shades of blue, which are really hard to see in daylight.
Absolutely, but that doesn't solve the problem that's talked about here (seeing the turn signal from the other side of the vehicle). It might be clearer what the turn signal is, but if you look at the right side of a vehicle, you won't be able to see the left headlight, even when it's massive.
How would that work? If you look from the side you suddenly don't see anything again, or an arrow point forwards or backwards?
If you look from the front, current turn signals work for that already.
Red is always on top (at least in Europe) so even color blind people know what the signal is.
How would you do that so it isn't ugly as hell and isn't prone to misunderstanding?
Just preinstall UnigetUI, call it Microsoft Store and be done with it.
And then they'd flash no matter which direction they'd turn?
So basically hazard lights all the time? Not sure if you still don't understand what this discussion is about and how I could make it any more clear.
