Your dog's Fi Collar has a built-in-LED light that can be customized to your pup's favorite color for added visibility in low light situations. It can be turned ON/OFF from the Fi App. To change the color of the light, see: How Do I Change My Fi Light on My Fi Collar?
Please note that the Fi Light is designed to flash instead of staying on at all times, and will turn off automatically after 30 minutes to preserve battery life. There may be a delay when you turn your light on. See below information regarding Light Connection Time.
