What caused this then?

The cowlings on the lower traffic light are definitely melted rather than smashed or dented.

Red and Amber on the top set not affected but green has the end of the cowling broken. That one looks snapped.

It is almost like something hot and dense crashed down at a steep angle going through the top green light and then melting the lower set as it passed them.

I shouldn’t have googled hot and dense

Baby robin on fire?

Car or bin fire below.

Someone in t’council a massive Dali fan.

Corporate death ray

She hates waiting at the lights.

Bin fire would explain the bottom melted ones but not the snapped top lights.

I am thinking it might be a fat burning baby robin

A Charizard escaping from a pokemon hunter

They’re not snapped the heat has damaged them too,

And the trim on the side of the top one that has been nearly knocked off?
