I've been messing about with the lights on the beautiful Alabeo Aztec, trying to get the nosewheel light to go off after the gear is retracted. I got it all to work by deleting all of the light entries. What's going on? Where is the light data stored, if not in the cfg? I would like to swap the nose wheel light for a brighter shockeave light, but since I can't see any lines of code here or in the panel.cfg, I don't really know what to do. Maybe I should call it quits and enjoy my little victory! :) 

You should find the light entries in the aircraft cfg file. Is this the file you are referring to? If so, there should be lines concerning all the lights per the following I pulled from the FSX A321.

[LIGHTS]        
//Types: 1=beacon, 2=strobe, 3=navigation, 4=cockpit, 5=landing
light.0 = 3, -19.10, -54.15,  5.85, fx_navredm ,
light.1 = 3, -19.10,  54.15,  5.85, fx_navgrem ,
light.2 = 3, -83.60,   0.00,  7.60, fx_navwhih ,
light.3 = 2, -18.60, -53.50,  5.75, fx_strobeh ,
light.4 = 2, -18.60,  53.50,  5.75, fx_strobeh ,
light.5 = 2,   3.70,   0.00, -2.80, fx_beaconb ,
light.6 = 1,  -3.30,   0.00, 11.50, fx_beaconh ,
//light.7 = 4,  53.41,   0.00,  4.50, fx_vclighth ,
