Sony is no stranger to idiosyncratic hardware design. Nintendo and Sega put analog sticks on their controllers in the '90s? Sony adds on an extra stick and redefines console controllers. Touch screens are de rigueur? Sony slaps a touch surface on the front and back of PS Vita. The PlayStation 4 is a sleek piece of modern consumer tech design, but even it's got its quirks.

Case in point: the Dualshock 4 light bar. Every PS4 controller looks like KITT fromKnight Rider, with a giant oblate spheroid of light pulsing on the front. Not just good for running down the battery, the light bar actually performs some unusual functions in a variety of games. Below the break is a taster's choice selection of memorable light bar uses from the PlayStation 4's first year of games. After browsing that, take our poll and discuss the light bar's career in the comments.
