A device made from a strobe light and a piece of infrared plastic that's used to change traffic lights which have Opticon sensors. Used by ambulenses and shady people to get through traffic quickly. Probably named chrome box because a strobelight reflector looks chrome-like. It's probably illegal in 75 states.
I save 45 minutes from my trip to work everyday with this chrome box foo, fuck da po-leece dey ain't never gonna katch me.
