Helles Blau in dunkler Nacht,
hat Eile und gibt Acht.
Es rotiert und blinkt so klar,
bringt Hilfe schnell, ist für uns da.
Das Blaulicht weist den Weg geschwind,
wo Not am Mann, bei Sturm und Wind.
Mach Platz, mach Bahn, es eilt herbei,
für Sicherheit und Polizei.

Bright blue in the dark night,
In a hurry, paying attention right.
It rotates and flashes so clear,
Brings help quickly, it is here.
The blue light shows the way fast,
Where there's need, in storm and blast.
Make way, clear the path, it rushes by,
For safety and the police nigh.

wer bin ich, schnell erkannt?

EN:
I shine blue, but am not the sky,
I turn in circles, without mold, oh my.

In emergencies and haste, side by side.
Often hand in hand with a loud sound,
Who am I, quickly found?

💡 More Interesting Facts

Word Composition:

The word "Blaulicht" is a compound noun, formed from:

  • blau: The adjective for the color blue.
  • Licht: The noun for light.

Trivia:

  • The color blue was chosen internationally for police and emergency vehicle warning lights because it stands out well from other light sources in traffic (e.g., red taillights, white headlights, yellow turn signals) and is highly visible even during the day.
  • In Germany, using only the Blaulicht (without the siren) does not automatically grant the emergency vehicle the right-of-way; it primarily serves as a warning or securing signal in such cases.

📝 Summary: is it der, die or das Blaulicht?

The answer is clear: It is always das Blaulicht (neuter).
