Configuration:
1. Set [UAVCAN_LGT_NUM](../advanced_config/parameter_reference.md#UAVCAN_LGT_NUM) to the number of lights (0 disables). You might need to reopen the ground station to have parameters for new instances available.
1. Set [UAVCAN_LGT_NUM](../advanced_config/parameter_reference.md#UAVCAN_LGT_NUM) to the number of lights (0-2, 0 disables).
You might need to reopen the ground station to have parameters for new instances available.
2. For each light slot (0 to NUM-1), set:
- `UAVCAN_LGT_IDx`: The `light_id` matching your peripheral.
- `UAVCAN_LGT_FNx`: `Status` for system status colours, or `Anti-collision` for white beacon.
3. For anti-collision lights, [UAVCAN_LGT_ANTCL](../advanced_config/parameter_reference.md#UAVCAN_LGT_ANTCL) controls when they illuminate (off, armed, prearmed, always on).
- `UAVCAN_LGT_FNx`: The light function. Available options:
- `Status`: System status colours from the LED controller.
- `Anti-collision` to `White Navigation`: Light functions controlled by `UAVCAN_LGT_MODE`.
- `Status / Anti-collision` to `Status / Off`: Hybrid modes that show status colours when `UAVCAN_LGT_MODE` is inactive, and switch to the second function when active.
3. [UAVCAN_LGT_MODE](../advanced_config/parameter_reference.md#UAVCAN_LGT_MODE) controls when navigation lights turn on (off, armed, prearmed, always on).
4. Reboot for any changes to take effect.
