tail lights

Reading some complaints about the night lighting of the tail turning on and off with the landing lights on the Ariane BBJ got me thinking about lighting in MSFS. If the lighting is controlled by the alpha channel of the light map, wouldn't it be impossible to turn the tail light on and off separately from the landing lights? I assume this issue would be the same with illumination caused by taxi lights.Is there a way to control these lights separately, in terms of the illumination they produce on the aircraft?Luhiss
