I was doing this on Altis if that matters.
put in the Init of "Land_PortableLight_single_F":
```
_light_emitter_0 = "#lightpoint" createVehicleLocal getpos this;
_light_emitter_0 setLightColor [1,1,1];
_light_emitter_0 setLightAmbient [1,1,1];
_light_emitter_0 setLightIntensity 5000;
_light_emitter_0 setLightUseFlare false;
_light_emitter_0 setLightDayLight true; //Issue here
_light_emitter_0 setLightAttenuation [15, 4, 5, 0];
_pos1 = this modelToWorldVisual (this selectionPosition "light_1_pos");
_pos2 = this modelToWorldVisual (this selectionPosition "light_1_dir");
_light_emitter_0 lightAttachObject [this, (this selectionPosition "light_1_pos")];
_light_emitter_0 setdir ( _pos1 getdir _pos2);
```
