Hello @FuuunBH

Your post was moved to #third-party-addon-discussion:aircraft since this is not a stock airliner.

Check your control bindings for all the hardware you have connected to the sim, look for anything bound to something similar to:

Set Landing Lights
Set Nav Lights
Set Taxi Lights.

Unbind them, and see if that makes a difference. My guess is, you have these lights bound to a control, and your hardware is actually set to have them on. So using the mouse to turn them off won’t work, because your control hardware is feeding the sim with the ON position.
