Bluetooth Lightbar is an application that makes it possible to control your Bluetooth-enabled light bar devices. You can adjust the brightness and color of the lights and use the device's built-in microphone to listen to the music in your environment.
You can also control the device's light mode and use its built-in speaker to play music stored in your device. The app will also allow you to use the device's built-in flash to flash the lights according to the rhythm of the music.
You can also add a timer to the device to automatically turn it off after a certain period of time.
