Traffic Light Thought - No lights, near hit, we need a signal!

Why isn't there an official way to tell another driver to light up?

Why would someone pull out of a petrol station directly in front of another car?

Well after sundown and it had no lights on at all. Flashing headlights didn’t alert them, the world needs an agreed warning signal for “turn on your lights’. Even with auto lights on newer cars it seems to be more and more common.
