Resubbed the mod and the light finally works

The red and green lights should have worked if you subscribed to the custom light effect mod and have it enabled. That's the only way to have a green light effect be attached to a non-vehicle asset.

Uhh coz I saw it in the description in game says red light and green light so I thought it will illuminate. Other lights works just fine, and yes I did subsribed to the custom light effect mod. Thanks a lot for the reply :)

I can't recall if this one has a light effect with it or not. I am going to guess that it probably doesn't since the description doesn't mention it (it's been a while since I have touched this asset).
As for the other lights, are you using the custom light effect mod? I believe it is listed as a required asset for those assets.

Hi, just subsribed to your airport works and wondering if this light will actually works. I tried both the red light and the green light but they were not showing any light at all.
