Lighting Control

External lights can be controlled via digital output (on supported devices). Control is managed through /io/in_light input and /misc/lightopts settings.

tip

• For UART display users: Set /io/in_light to 3,14 to utilize the display's light input
• If you wish to extend the lighting system to cover turn signal lights, please contact our support team.
