Anyone in Los Angeles want to help me with a wacky prank? I want to do something like make all the lights at an intersection flash red. I also want to turn traffic signals around so they face the wrong way and mix up the audible signals for blind people. I have access to a cherry-picker truck, so we can turn signals around.

What's that you say? This is most likely highly illegal, and these aren't pranks or the actions of a trickster, these are highly dangerous sociopathic ideas?

Well, apparently not to the AP, since they described someone who's doing these things in Sunnyvale as a "prankster" and a "trickster" rather than more appropriate language. Details in "Calif. Prankster Changing Traffic Lights".
