What is wrong with my SpotLight script? [UNANSWERED]

I added a night/day cycle script to my game, and it is working very good. So, I decided to add a light column (that works with SpotLight). Then I added a script to the SpotLight, this script is supposed to make the spot light opens in night(19:00:00) and close after 600 seconds(5:00:00). But the script is not working, here is the script:-

Lighting.Parent.TimeOfDay:connect(function(Time)
	if TimeOfDay = 19 then
		SpotLight = true
		while wait(600)
		SpotLight = false
	end
end

Here is the day/night cycle script if you want to know if it is wrong, note that I don't have troubles with this script:-

local dayLength = 24

local cycleTime = dayLength*60
local minutesInADay = 24*60

local lighting = game:GetService("Lighting")

local startTime = tick() - (lighting:getMinutesAfterMidnight() / minutesInADay)*cycleTime
local endTime = startTime + cycleTime

local timeRatio = minutesInADay / cycleTime

if dayLength == 0 then
	dayLength = 1
end

repeat
	local currentTime = tick()
	
	if currentTime > endTime then
		startTime = endTime
		endTime = startTime + cycleTime
	end
	
	lighting:setMinutesAfterMidnight((currentTime - startTime)*timeRatio)
	wait(1/15)
until false

NOTE: I am new to scripting, so you will find lots of mistakes.

Thanks for helping.

In line 1 of your spotlight script, you connect to Lighting.Parent.TimeOfDay, but no event. You might want to try Lighting.changed:connect(, etc. In line two, you access the TimeOfDay property. That property is actually a string, so to compare, you should check if TimeOfDay equals '19:00:00'. A full spotlight script is provided below with other enhancements.

game.Lighting.changed:connect(function() --connect when a lighting property changes
	local myTime = game.Lighting.TimeOfDay --set myTime equal to lighting's TimeOfDay
	if myTime == '19:00:00' then --if its 1900 hours then
		SpotLight.enabled = true --enable the spotlight. Double check me if enabled is capitalized or not.
	else if myTime == '5:00:00' --if it's not 1900 then if it's 0500 then
		SpotLight.enabled = false --disable the spotlight
	end --close the if statement
end) --close the connect line

I will add a 'while true do', since i know best using this one. So, add a while true do in a new script:

while true do

wait()
end

Okay, now let's make the part of disable and enable.

if game.Lighting.TimeOfDay == 19 then
SplotLight.Enabled = true
end
if game.Lighting.TimeOfDay == 5 then
SpotLight.Enabled = false
end

Try that, reply if it doesn't work and tell me what you see in output
