effect for strobe sequence

Hi after a year of modeling and texturing on spare time I am stuck on a problem for crate the sequenze for the IGS approch light .As you can see in this image there are several tower with one effectlight each example tower01.bgl have attach tower01.fx and so on)I was thinking to change the LIFE value on the emitter section to have a enlight sequence from tower01 to the last on increment the Lifetime=0.00, 0.50 for tower01 and Lifetime=0.00, 1.00 for tower02 and so on but no manage to workout even on change the DELAY maybe with a CONTROLLER will work but how to setup for that kind of action I don't know.To see the correct sequence is clear on this video:

I was searching on the .asm 0.asm file to find the atteched .fx effect but i don't find, I was thinking to change the effect name on those file and recompile with bglc_9.exe insted of re export from gmax.Thank'sFabrizio[Library Effect]Lifetime=5Version=2.00Radius=-1Priority=0[Properties]Spot=1Tower=1Map=1Cockpit=1VirtualCockpit=1[Emitter.0]Lifetime=0.00, 0.50Delay=0.00, 0.00Bounce=0.00No Interpolate=1Rate=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, 0.00[Particle.0]Lifetime=0.00, 0.00Type=19X Scale=5.00,5.00Y Scale=5.00,5.00Z Scale=5.00, 5.00X 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, 0.00X 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, 0.00Static=1Face=1, 1, 1[ParticleAttributes.0]Blend Mode=2Texture=fx_2.bmpBounce=0.00Color Start=100, 100, 150, 200Color End=100, 100, 150, 0Jitter Distance=0.00Jitter Time=0.00uv1=0.00, 0.00uv2=0.50, 0.50X Scale Goal=0.00Y Scale Goal=0.00Z Scale Goal=0.00Extrude Length=0.00Extrude Pitch Max=0.00Extrude Heading Max=0.00http://img159.imageshack.us/my.php?image=igsdx1.jpg
