PlayStation 4 controller light won't switch off

Players won't be able to switch off the light which emanates from the front of the PlayStation 4's controller, Sony president of worldwide studios Shuhei Yoshida has confirmed.

When asked on Twitter if the PS4's light bar could be switched off to save battery, Yoshida responded with a firm "no."

The light bar on the DualShock 4 controller is designed to work with the PlayStation 4 camera to detect motion, similar to the Move controller. The light can also be used for system functions, such as letting players know when the battery is low, and by developers; Killzone: Shadow Fall uses the light bar to give an indication of the players' health.

Along with the light bar, the DualShock 4 features a mono speaker, a 3.5mm headset jack, a micro USB port, and a clickable touch pad on the front of the controller.

The PlayStation 4 will be released later this year for $399.
