@rmbell34 From my understanding that is not a player light, that light tells you what mode the controller is in. From the website.
What are the four small LEDs for on the bottom of the controller?They are controller mode indicators:
A. LED 1 blinking: D-input mode
B. LED 2 blinking: X-input mode (Xbox 360 mode)
C. LED 3 blinking: macOS mode
D. LED Rotating: Switch mode or pairing mode
E. Solid LED: connection is successful
*It also indicates the player mode when connected to Switch.
