Strange lighting in P3Dv3

[wombat666]

Or is it just Flak??
Carenado EMB Phenom on an early test flight in P3Dv3, as soon as I switched to external view it lit up like this!!!
Temporarily parked while I look through the lighting in the cfg, any thoughts would be most welcome.
No trouble in either FSX or P3Dv2, and no similar problems so far with other Carenado or Alabeo GA.

These look very much like the textures that are used in the nav light effects:

It seems just placed as a whole without correct coordinates and scale. Looks like a corrupt effect file. I do not have the plane though to check.

Thanks for the advice!
Reloaded the aircraft and the effects files and no more 'Flak'.
