How do you make a light that flicker when it is evening/18:00:00?

Hello,

I have a little problem and is easy to be fixed I guess but I don't know how.

I have streetlights in my game and they must pretend to be broken.

My intention was that they will start flickering at 6PM (18:00:00) till 6AM (06:00:00).

The problem is they stop flickering when it is midnight/00:00:00.

Line 25 to 29 is the flickering part.

Here the script.

local Lights = workspace:WaitForChild('Lights')
local BrokenStreetLights = Lights:WaitForChild('BrokenStreetLights')
local Lighting = game:GetService('Lighting')

function SetLights(bool)
    if bool == "on" then
        for i,v in pairs(BrokenStreetLights:GetDescendants()) do
            if v:IsA('SpotLight') and v.Parent:IsA('BasePart') then
                v.Enabled = true
                v.Parent.Material = Enum.Material.Neon
                v.Parent.Transparency = 0
            end
        end
    elseif bool == "off" then
        for i,v in pairs(BrokenStreetLights:GetDescendants()) do
            if v:IsA('SpotLight') and v.Parent:IsA('BasePart') then
                v.Enabled = false
                v.Parent.Material = Enum.Material.Glass
                v.Parent.Transparency = .25
            end
        end
    end
end

while wait() do
    if Lighting.TimeOfDay >= "18:00:00" then
        SetLights("off")
		wait(0.05)
        SetLights("on")
    elseif Lighting.TimeOfDay >= "06:00:00" then        
        SetLights("off")
    end
end

I hope someone can help me. Keep in mind im a beginning scripter.

Hey, to solve your problem you should use GetPropertyChangedSignal. Here's an example on how you'd use it in your case.

local Lighting = game:GetService("Lighting")

Lighting:GetPropertyChangedSignal("TimeOfDay"):Connect(function()
	if Lighting.TimeOfDay == "18:00:00" then
		SetLights("off")
		wait(0.05)
		SetLights("on")
	elseif Lighting.TimeOfDay == "06:00:00" then
		SetLights("off")
	end
end)
