# The LED Command

LED is a Ducky Script command for the Signal Owl to control the Red LED status indicator. It accepts either a pattern, or a common payload state.

### LED PATTERNS

| -------- | -------------------------------------------------------- |
| SOLID    | *Default* No blink. Used if pattern argument is ommitted |
| SLOW     | Symmetric 1000ms ON, 1000ms OFF, repeating               |
| FAST     | Symmetric 100ms ON, 100ms OFF, repeating                 |
| VERYFAST | Symmetric 10ms ON, 10ms OFF, repeating                   |

### LED STATE

These standardized LED States may be used to indicate common payload status. The basic LED states include **SETUP**, **FAIL**, **ATTACK**, **CLEANUP** and **FINISH**. Payload developers are encouraged to use these common payload states. Additional states including multi-staged attack patterns are shown in the table below.

| STATE    | COLOR PATTERN | Description                                 |
| -------- | ------------- | ------------------------------------------- |
