Why does the app only display the interior lighting option and not the underbody after adding more lights?Updated an hour ago

This may occur due to a short in the lighting system or control box, which can disable the underbody lights and prevent them from appearing in the app. Another possibility is that an interior-only Bluetooth control box was installed, which does not support underbody lighting.

Check for wiring damage or shorts, ensure you are not trying to connect multiple control boxes, and verify that all lights were installed correctly. If the issue persists, the control box may need replacement.
