This works for me in "mapname".scar, don't know if the "Time of Day" has to be set to night tho.(Scenario->Atmosphere Properties-> Sunlight)
Code
function OnInit()
EGroup_SetAnimatorState(eg_lamps, "Light_State", "On")
EGroup_SetAnimatorState(eg_lamps, "Light", "On")
--call custom functions here.
end
--add custom functions here.
Scar_AddInit(OnInit)
--this is a comment btw
