| Option | Default Value | Description |
|--------|---------------|-------------|
| `RGBLIGHT_ANIMATIONS` | | `#define` this to enable animation modes. |
| `RGBLIGHT_EFFECT_SNAKE_LENGTH` | 4 | The number of LEDs to light up for the "snake" mode. |
| `RGBLIGHT_EFFECT_KNIGHT_LENGTH` | 3 | The number of LEDs to light up for the "knight" mode. |
| `RGBLIGHT_EFFECT_BREATHE_CENTER | 1.85 | Used to calculate the curve for the breathing animation. Valid values 1.0-2.7. |
| `RGBLIGHT_EFFECT_BREATHE_MAX | 255 | The maximum brightness for the breathing mode. Valid values 1-255. |
| `RGBLIGHT_EFFECT_SNAKE_LENGTH` | 4 | The number of LEDs to light up for the "snake" animation. |
| `RGBLIGHT_EFFECT_KNIGHT_LENGTH` | 3 | The number of LEDs to light up for the "knight" animation. |
| `RGBLIGHT_EFFECT_KNIGHT_OFFSET` | 0 | Start the knight animation this many LEDs from the start of the strip. |
| `RGBLIGHT_EFFECT_KNIGHT_LED_NUM` | RGBLED_NUM | The number of LEDs to have the "knight" animation travel. |
| `RGBLIGHT_EFFECT_CHRISTMAS_INTERVAL` | 1000 | How long to wait between light changes for the "christmas" animation. Specified in ms. |
