Did another search and saw issue 165 (similar). My issue is ai.xml code to turn lights on in model aircraft in AI system. Had no effect, on or off. Verified lights did work with other methods.

The path "sim/time/sun-angle-rad" would be interpreted as a relative path (based on the aircraft's root property). You should use an absolute path:
/sim/time/sun-angle-rad
and things should work ok (note the difference with the leading "/").
Usually AI aircraft need to use relative paths, since an AI aircraft should not reference the main simulator aircraft's speed/orientation/etc, but it's own speed/orientation/etc. However, when you want to access global properties, not specific to the AI aircraft itself, you need to use absolute paths.

Status: Invalid

Right again, I verify absolute path works. Sorry for the mistake!
