How to trigger an effect using XML ?

[visade]

I know a little bit of XML, just XML, and I would like to know how I could link an effect (a navigation light) to a FS2004 variable (beacon lights on).

Thanks in advance, regards.

Most of the time, .fx files are assigned in the [Effects] section of the aircraft.cfg, which includes their "Type#" electrical bus:

[LIGHTS]
//Types: 1=beacon, 2=strobe, 3=navigation, 4=panel, 5=landing, 6=taxi, 7=recognition, 8=wing, 9=logo 10=cabin
light.0=3, -1.4353, -17.785, -0.107, fx_navred
light.1=3, -1.4353, 17.785, -0.107, fx_navgre
light.2=2, -1.705, -17.931, -0.107, ESDGstrobe
light.3=2, -1.705, 17.931, -0.107, ESDGstrobe
light.4=8, -0.0, 0, 1.7 , esdg_C400_panelflood_lo // tied to Overhead switch
light.5=9, 0.0, 0, 1.7 , esdg_C400_panelflood_med // tied to Overhead switch
light.6=10, 0.0, 0, 1.7 , esdg_C400_panelflood_hi // tied to Overhead switch
