Too small to see. You can be paying attention to the road, and those small led blinkers will go unnoticed most of the time.

That, and the fact that a lot of them are too small.

What about a gradual alarm?

It starts with low volume, then gradually increases volume.

There’s even smart lamps that do increasing light intensity to simulate sunrise.
