    # Example configuration entry
    light:
      - platform: binary
        name: "Desk Lamp"
        output: light_output

    output:
      - id: light_output
        platform: gpio
        pin: GPIO16

Configuration variables:
------------------------

- **name** (**Required**, string): The name of the light.
- **output** (**Required**, :ref:`config-id`): The id of the
  binary :ref:`output` to use for this light.
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
- **effects** (*Optional*, list): A list of :ref:`light effects <light-effects>` to use for this light, though binary lights
  only support very few of them.
- All other options from :ref:`Light <config-light>`.
