For convenience, you can use the `IS_HOST_LED_ON(led_name)` and `IS_HOST_LED_OFF(led_name)` macros instead of calling and checking `host_keyboard_leds()` directly.

## Setting physical LED state
## Setting Physical LED State

Some keyboard implementations provide convenience methods for setting the state of the physical LEDs.

### Ergodox and Ergodox EZ
### Ergodox Boards

The Ergodox EZ implementation provides `ergodox_right_led_``1`/`2`/`3_on`/`off()`
to turn individual LEDs on and off, as well as
`ergodox_right_led_on`/`off(uint8_t led)`
to turn them on and off by their number.
The Ergodox implementations provide `ergodox_right_led_1`/`2`/`3_on`/`off()` to turn individual LEDs on or off, as well as `ergodox_right_led_on`/`off(uint8_t led)` to turn them on or off by their index.

In addition, it is possible to specify the brightness level with `ergodox_led_all_set(uint8_t n)`,
for individual LEDs with `ergodox_right_led_1`/`2`/`3_set(uint8_t n)`
or by their number using `ergodox_right_led_set(uint8_t led, uint8_t n)`.
In addition, it is possible to specify the brightness level of all LEDs with `ergodox_led_all_set(uint8_t n)`; of individual LEDs with `ergodox_right_led_1`/`2`/`3_set(uint8_t n)`; or by index with `ergodox_right_led_set(uint8_t led, uint8_t n)`.

It defines `LED_BRIGHTNESS_LO` for the lowest brightness and `LED_BRIGHTNESS_HI` for the highest brightness, which is also the default.
Ergodox boards also define `LED_BRIGHTNESS_LO` for the lowest brightness and `LED_BRIGHTNESS_HI` for the highest brightness (which is the default).
