Light can be created with command [createVehicleLocal](../commands/createVehicleLocal.md) with special vehicle class `"#lightpoint"`

for example:

```sqf
_light = "#lightpoint" createVehicleLocal _posAGL;
_light setLightBrightness 1.0;
_light setLightAmbient [0.0, 1.0, 0.0];
_light setLightColor [0.0, 1.0, 0.0];
_light lightAttachObject [_object, [0,0,0]];
```
