The verb ‘sein’ must agree with the singular subject ‘was’, not the plural ‘Lichter’.
Wenn die Lichter blinken, ist was los gerade.
‘gerade’ should stay before ‘was’, not after ‘ist’.

In this idiom the adjective ‘los’ follows ‘sein’, not precedes it.

Cultural Tip
‘Was los sein’ is a colloquial German expression that works like English ‘what’s up?’ or ‘something’s up.’ It’s best used in casual settings; in formal contexts you would replace it with ‘etwas geschieht’ or ‘etwas passiert.’ Also, Germans often associate flashing lights with parties, clubs, or emergency vehicles, so the phrase can carry a slightly playful or urgent tone depending on the situation.
