So do you think you can reliably tell the difference between SAE Yellow (modern indicators - ECE stopped using amber years ago) and the yellowy warm-white daytime lights? I hope you don't discover you're wrong in practice because that could be painful!

Yellowy warm-white daytime lights?
Never seen them, they're always bluey white ime.

Plenty of current cars still use yellowy incandescent lights for daytime running lights. Fiat 500 for example. Look a few up on https://am-application.osram.info/en

So it's a different colour, in a different place and is animating to boot!

On some cars, maybe. They're pretty rare IME, much rarer than those with similar-colour solid lights right next to each other.

Really? This is reminding me of the engineer in the "Black Sheep" joke from https://www-users.cs.york.ac.uk/susan/joke/3.htm

You know of other cars that turn off the side that's indicating? Genuine question, I've only ever seen it on an Audi.

Now the rear of cars I do have problems with. Small indicators hidden in the middle of clusters of closely packed lights - particularly when braking!

Lots of new cars should, to comply with United Nations E/ECE/324/Rev.1/Add.47/Rev.12 Regulation 48 section 6.19.7. The main exception is where the lights are more than 2 inches apart and not part of the same electrical connections, but are there many like that?
