Many controllers support the concept of a light indicator to represent the player index of a controller. This is helpful to the user to know which player character is being controlled without testing each controller. Additionally, some games are only playable using a controller with a specific player index. In the context of VR, controllers may support a light indicator to assist the application in determining the location of the player. Light indicators range from monochrome light indicators (ON/OFF) to RGB light indicators.

We'd like to bring gamepad extension support to the same level of support provided by native functionality with the following proposal: Light Indicator Proposal
