Red light on a PlayStation 4 controller can be a nuisance, but there are ways to fix it. Here are three tips:

  1. Use a light bulb. Place the bulb in the center of the red light area on the controller and turn it off. This will help to reduce the amount of red light that is coming from the controller.
  2. Use a remote control. If you cannot find a light bulb or remote control, try using one of those instead. Remote controls have more range than bulbs, so they should be able to reach all of the red light areas on the controller.
  3. Use an app. If none of these methods work for you, you can try using an app like PS4 Controller troubleshooting tool or Troubleshooting Guide for PlayStation 4 controllers
