How to Dim the Lights on the PlayStation DualShock 4 Controller
The DualShock 4’s light bar is a neat thing. It works with many games to mimic what’s happening on the screen—in The Last of Us, for example, it will change colors as your health degrades, and turn red as you die. It’s a little thing, but it’s cool. The downside is that it’s also a battery hog, causing the controller to die much quicker than most of us would like. Thankfully, you can dim it.
