Effects do not appear when arriving at airport

Some guys of you I know from scenerydesign.org but there we did not come to a solution, so I try it here.We try to do apron lights by effect. We found the "fx_whitedot.fx" and altered it to get a really fine apron light. That's the source:==================================[Library Effect]Lifetime=5Version=2.00Display Name=Lamp Spot effectRadius=200Priority=0[Properties]Cockpit=1VirtualCockpit=1Spot=1Tower=1Map=1[Emitter.0]Lifetime=0.50, 0.50Delay=0.00, 0.00Bounce=0.00Rate=1.00, 1.00X Emitter Velocity=0.00, 0.00Y Emitter Velocity=0.00, 0.00Z Emitter Velocity=0.00, 0.00Drag=0.00, 0.00X Particle Velocity=0.00, 0.00Y Particle Velocity=0.00, 0.00Z Particle Velocity=0.00, 0.00X Rotation=0.00, 0.00Y Rotation=0.00, 0.00Z Rotation=0.00, 0.00X Offset=0.00, 0.00Y Offset=0.00, 0.00Z Offset=0.00, 0.00Pitch=0.00, 0.00Bank=0.00, 0.00Heading=0.00, 0.00[Particle.0]Lifetime=0.00, 0.00Type=19X Scale=40.00, 40.00Y Scale=40.00, 40.00Z Scale=0.00, 0.00X Scale Rate=0.00, 0.00Y Scale Rate=0.00, 0.00Z Scale Rate=0.00, 0.00Drag=0.00, 0.00Color Rate=0.00, 1.00X Offset=0.00, 0.00Y Offset=0.00, 0.00Z Offset=0.00, 0.00Fade In=0.00, 0.00Fade Out=0.00, 0.00Rotation=0.00, 0.00Ground Normal=1Shade=0Static=1Face=0, 0, 0[ParticleAttributes.0]Blend Mode=2Texture=fx_EDDB_spot.bmpTextureSize=256Bounce=0.00Color Start=100, 100, 100, 100Color End=16, 16, 16, 128Jitter Distance=0.00Jitter Time=0.00uv1=0.00, 0.00uv2=1.00, 1.00X Scale Goal=0.00Y Scale Goal=0.00Z Scale Goal=0.00Extrude Length=0.00Extrude Pitch Max=0.00Extrude Heading Max=0.00==================================It works pretty well, when you start at the airport, but it does not appear, when you start more than 10 miles away :(I altered a lot of the parameters, but nothing changed!Then we tried with a controller ... that one:===================================[Library Effect]Lifetime=5Version=2.00Radius=-1Priority=0[controller.0]lifetime=0.0, 0.0type=3distance=5000.00, 5000.00delay=7200.00, 7200.00x offset=0.00, 0.00y offset=0.00, 0.00z offset=0.00, 0.00effect.0=fx_EDDB_spot, 0.00, 0.00, 0.00, 0.00, 0.00, 0.00, 0.00, 0.00==============================Now the lights shine bright, when you arrive from more than 5000 meters away ("distance = 5000.0, 5000.0"), but not, when you start at the airport! That's what I call a dilemma :(((((((When I use NO controller, the lights do not shine, when I arrive (I don't have a clue, why!) and when I use a controller, the lights don't shine, when I start at the airport: I assume, I have dynamically to GET under that 5000 m distance for the controller to switch in. When I start under the distance of 5000 m, the controller does not start its work, because I did not PASS the 5000m distance. When I use "distance = 0, 5000" the controller picks a random distance between these two values to start its work.Can anybody help me to solve this? I need a working effect, even when starting from distant airports or a workaround on the controller ... PLEASE!!!!!
