Placing Chemlights on the map, How?

Was watching the Arma 3 Showcase Trailer, and found they had placed Chemlights on the ground. Looked really cool! But how did they do? Can someone try to help how to place Chemlights in the Editor on the ground.

Put a game logic (F1) where you want the chem light, set the condition of presence to

isServer

Put this in the init field:

0 = createVehicle ["Chemlight_blue",getPosATL this,[],0,"NONE"];

Thank you so much, will test it! ;)
