Maule M7 260C Paint 1, aircraft lights not working as installed in P3D v4.5. I'm surprised that P3Dv5 failed to fix this. Find your Aircraft.cfg file in your P3d installation directory and open it with text document editor. Scroll to near bottom of file and look for [Lights] which will look like this: [LIGHTS] //Types: 1=beacon, 2=strobe, 3=navigation, 4=cockpit, 5=Landing, 6=taxi //light.0 = 3, -1.23, -16.61, 3.08, fx_navred //light.1 = 3, -1.23, 16.61, 3.08, fx_navgre //light.2 = 3, -17.05, 0.00, 4.85, fx_navwhi //light.3 = 2, -1.23, -16.61, 3.08, fx_strobe //light.4 = 2, -1.23, 16.61, 3.08, fx_strobe //light.5 = 4, -2.24, 0.00, 2.20, fx_vclight The table above was provided by P3D's aircraft.cfg file, version Prepar3D_v4_Professional_4.5.13.32097 and also in V5. Light switches on Saitek switch panel operated properly with programming provided by SpadneXt. However, switches failed to illuminate lights on aircraft because all six lighting lines (above) were commented (with //) and therefore failed to execute. Removed slashes and lights then illuminated with the Saitek panel switches. I modified the above table in aircraft.cfg with the following table: [L[LIGHTS] //Types: 1=beacon, 2=strobe, 3=navigation, 4=cockpit, 5=landing, 6=taxi // Axis: Lon Lat vert Measured in feet from aircraft CG. Reset P3D profile after changes. light.0 = 3, -1.23, -16.61, 2.60, fx_navred light.1 = 3, -1.23, 16.61, 2.60, fx_navgre light.2 = 3, -17.05, 0.00, 4.85, fx_navwhi light.3 = 2, 1.50, -11.80, 2.00, fx_strobe //Left light.4 = 2, 1.50, 11.80, 2.00, fx_strobe //Right light.5 = 4, -2.24, 0.00, 2.20, fx_vclight //Cockpit panel light.6 = 6, 0.00, 0.00, 2.80, fx_taxiBlue light.7 = 5, 16.00, 0.00, -4.08, fx_landing light.8 = 1, -14.50, 0.00, 4.50, fx_beacon //Upper light.9 = 1, -8.00, 0.00, -1.00, fx_beacon //Lower The following light circuit codes apply per http://www.prepar3d.com/SDKv3/LearningCenter/simobjects/aircraft_configuration_files.html#lights. Code Switch 1 Beacon 2 Strobe 3 Navigation or Position 4 Cockpit 5 Landing 6 Taxi 7 Recognition 8 Wing 9 Logo 10 Cabin 11 General 12 Headlight 13 Brake The first entry of the line (light.0 to light.n) defines which light circuit, or switch, that the light is connected to (see the code table above). Multiple lights may be connected to a single switch. The next three entries Longitudinal, lateral and height, respectively) are the position relative to datum reference point. The final entry is the special effect file name that is triggered (for example, fx_navred). These files have .fx extensions and are located in my P3D installation folder: H:\P3Dv4.5\Prepar3D_v4_Professional_4.5.13.32097\Effects Positions of aircraft components are given relative to the datum reference point for the aircraft, in the order: longitudinal, lateral, vertical. The convention for positions is positive equals forward, to the right, and vertically upward. Units are in feet. you may want to tweak the exact position of the red Beacon light since I don't know exactly where the upper and lower lights belong. The datum reference point itself is specified in the weight_and_balance section of the SDK document.

Hello all, I'm having aircraft lighting issues in FSX. Most aircraft lights are working just fine, but some are not, as evidenced in the screenshots I have provided. I tried editing the aircraft.cfg files to no avail, and am wondering if the developer is to blame here. Can anyone help me out? Thank you for any assistance. 1. QWSim 757 2. SkySim DC-9-10 3. Carenado C208B All of the other variations of the aforementioned aircraft types have lighting issues as well; these pics are just samples.
