Is there a good way to set the rotation and orientation of the SpotLight to match the attitude of the model?

I implemented Spot Light by referring to osglight.cpp.

However, it is having difficulty in implementing SpotLight to change direction according to the heading of the aircraft at the same location.

Even if I get the Pitch, Roll, and Heading values of the aircraft and set the values in the Direction of Light, even if I add them to the osg::PositionAttitudeTransform object and set the values in setAttitude(), the desired result is not obtained.

In common sense, I think you can only rotate the SpotLight's z axis to match the aircraft's heading... The result is not implemented as expected.

Is there a good way to set the rotation and orientation of the SpotLight to match the attitude of the model?
