+The `status_led` light platform allows a single LED to indicate the status of
+the device (such as an error/warning state) or as a binary light (such as an OK state).
 This is useful for devices with only one LED available.
 You can also use a binary [Output Component](#output).
 
 It provides the combined functionality of {{< docref "/components/status_led" "status_led component" >}} and a
 {{< docref "/components/light/binary" "binary light component" >}} over a single shared GPIO led.
 
-When the device is on error/warning state, the function of `status_led` will take precedence and control the blinking of the LED.
+When the device is in error/warning state, the function of `status_led` will take precedence and control the blinking of the LED.
 When the device is in OK state, the LED will be restored to the state of the `binary light` function and can be controlled as such.
