Regarding this, how do I turn off the light on my ps4 controller?
On the Home screen (the main interface) of yourPS4, scroll up to the Function area and select Settings-> Devices -> Controllers -> Brightness ofDUALSHOCK 4 Light Bar. You will then have your choice ofhaving your light bar brightness set to Bright (Standard),Medium, or Dim.
One may also ask, why is the light on my ps4 controller yellow?
A blinking yellow light indicates thecontroller was just plugged in to charge. A yellowlight on the controller all the time while the system ispowered on, regardless of game, means that controller isplayer (3 or 4, cannot remember which).
The PS4 controller flashing white issue isgenerally caused by two reasons. One is because of the lowbattery, and that means that you need to charge your PS4controller to make it back on track. The other reason isthat your controller is trying to connect to yourPlayStation 4, but failed due to unknownfactor(s).
