Applight visible only from one direction?

[Jan Tore Elvheim]

Hello,
I've helped a fellow Norwegian scenery designer with some objects for ENSD and I need some help with the light effect on some approachlight poles

I want them to be visible only on landing direction and not from over the runway, any help?
I'm way outside my comfort zone with these effectfiles

I've used the obslight2 as base and edited from that:

Have you tried to change the 'face=1,1,1' to something else? Not sure it helps but 1,1,1 means that the effect particles are always facing the user, however, in this case i think it should be one direction (heading) only (1,1,0?).

Thanks for the tip, one step further
It is now locked in the axis I want, but still viewable from both directions (Face 0,0,0)
