Solved Dynamic Lighting on map

Is there a method of setting up dynamic Lighting (lights with only activate at night) on a map?
I've seen that some maps contain them (Nadeox1's VR_city for example)

I think it would be a cool addition to the map I'm working on.

Thanks in advance

Solved.
Used the data from @Nadeox1's VR_city map to create the effect I wanted
The file I used was mainLevel.lua

Spoiler

Code:

local M = {}

local function setAllLightsEnabled(group, value)
    for i = 0, group.obj:getCount(), 1 do
        local id = group.obj:idAt(i)
        local obj = scenetree.findObjectById(id)
        if obj and obj.obj:isSubClassOf('LightBase') then
            obj.obj:setLightEnabled( value )
        end
    end
end

local lastValue = nil

local function onUpdate()
    local tod = scenetree.tod
    if not tod then return end

    local value = true
    if tod.time > 0.1 and tod.time < 0.5 then
        value = false
    end

    if lastValue == value then return end
    lastValue = value

    if scenetree.DynamicLights then
      setAllLightsEnabled(scenetree.DynamicLights, value )
    end
    if scenetree.MissionLights then
      setAllLightsEnabled(scenetree.MissionLights, value )
    end
end

M.onUpdate = onUpdate

return M
