    Deprecates system-specific indicator LEDs as redundant.
    The ``SYSTEM_INDICATOR_LED_LIT``, ``SYSTEM_INDICATOR_LED_BLINKING``,
    ``SYSTEM_INDICATOR_LED_OFF`` and ``SYSTEM_INDICATOR_LED_UNKNOWN`` constants
    should not be used. Generic indicator LED constants should be used instead.
    Those are ``INDICATOR_LED_LIT``, ``INDICATOR_LED_BLINKING``,
    ``INDICATOR_LED_OFF`` and ``INDICATOR_LED_UNKNOWN`` respectively.
