Time detector not working (attempt to compare number < string)

[DidiSharkYiatCraft (Shark)]

What I’m trying to do is to make the part glow at night. I figured out that setting the reflectance to a negative value at night makes the part glow. This script is intended to control the reflectance value based on the time of day, but it’s not working. I’d love some help.

game.Lighting.Changed:Connect(function(ClockTime)
	if ClockTime > 18 or ClockTime < 6 then
		script.Parent.Reflectance = -8
		script.Parent.SurfaceLight.Enabled = true
		end
	if ClockTime < 18 or ClockTime > 6 then
		script.Parent.Reflectance = 0
		script.Parent.SurfaceLight.Enabled = false
		end
end)

script.Parent.Reflectance = 0
		script.Parent.SurfaceLight.Enabled = false

I hope i helped you with this tutorial :3

local Lighting = game:GetService("Lighting")

Lighting:GetPropertyChangedSignal("ClockTime"):Connect(function()
	local Y: number = Lighting:GetSunDirection().Y -- Sun Direcrtion it's should be from -1 into 1
	
	if Y < 0 then -- night time should be from 0 into -1
		print("NightTime")
	else -- sun time should be from 0 into 1
		print("SunTime")
	end
end)

You are doing it wrong. When you do game.Lighting.Changed, it fires when any property of the Lighting service changes and you’re getting the ClockTime through the arguments, which actually doesn’t exist.

The first argument of the Changed event is actually the name of the property. However, it is recommended that you don’t use the Changed property.

Instead use the GetPropertyChangedSignal method.

local Lighting = game:GetService("Lighting") -- using `GetService` is a better way to access services

Lighting:GetPropertyChangedSignal("ClockTime"):Connect(function()
    -- don't do multiple if's, instead do `elseif`
    if Lighting.ClockTime > 18 or Lighting.ClockTime < 6 then
        script.Parent.Reflectance = -8
        script.Parent.SurfaceLight.Enabled = true
    elseif ClockTime < 18 or ClockTime > 6 then
        script.Parent.Reflectance = 0
        script.Parent.SurfaceLight.Enabled = false
    end
end)
