How many lights can you control?

[ggiarda]

In many cases (for example Carenado airplcrafts) aircraft show lights that cannot be controlled by modifications on aircraft.cfg file.
For example in Carenado C172N aircraft.cfg I made these modifications

[LIGHTS]
//Ty]pes: 1=beacon, 2=strobe, 3=navigation, 4=cockpit, 5=landing, 6=taxi
light.0 = 3, -3.49, -17.14, 2.52, fx_shockwave_navred //fx_navredalabeo172
light.1 = 3, -3.45, 17.14, 2.52, fx_shockwave_navgre //fx_navgrealabeo172
light.2 = 1, -20.86, 0.00, 5.30, fx_shockwave_beacon //fx_beaconalabeo172
light.3 = 4, -2.57, 0.00, 1.60, fx_shockwave_vclight //fx_vclightalabeo172
light.4 = 5, 3.15, 0.25, -1.00, fx_shockwave_landing_light_low_old
light.5 = 6, 3.15, -0.25, -1.00, fx_shockwave_landing_light_low_old
light.6 = 5, 3.15, 0.25, -1.00, fx_shockwave_landing_light_light_sm

those in red are default settings.
But in the image can't upload, there is a tail navigation light, which I cannot modify or delete.

Same problem shows for "ground landing light reflections" which cannot be deleted even if you've deleted the landing light config line!
Where are these commands in FSX? Are they modifiable?
Thanks in advance to everyone who'll send a reply
