Lights out of order Verkeerslichten buiten werking
De regel · The rule
Flashing amber lights give nobody priority: the signs apply, and where there are none, priority to the right.
RVV 1990 art. 15, 75

Why this rule exists
When lights fail, the junction falls back to the basic rules: slow down and read the signs.
