Can you show how you are handling the lights off then? the script
I’m using math.random() to turn off the lamps. The script is on each lamps
You gotta be more descriptive or show the script. You mean, a player idk clicks a button, and randomly you choose a lamp to turn off? The warning will show only when all lights are disabled
Every random seconds one of the lights will turn off automatically. And at some possibilities all the lights will turn off at the same times and at that point something happens.
And how you are disabling the light by changing what into the SpotLight? The script consider the property Enabled to run, not any other like bringing down the Brightness
Testing the script vid:
I’m turning off the light using Enabled = false.
so you’re trying to make one of the lights randomly turn off every random duration, and there would be a chance for all the lights to turn off at the same time then something would happen, right?
if i’m right, i’ll be writing a script for you in a moment…
Check the video I added into my previous message, Im testing the script and it works normally.
Add a print in the changed signal event to debug:
light:GetPropertyChangedSignal("Enabled"):Connect(function()
warn("Got Signal")
if CheckAllLights() then
I think thats what @bagussetya11 wants!
Thats the importance to be descriptive in the initial post or at least show some code… None of the code me and others suggested is intended to work like that 
Yeah maybe code before these lines could be wrong too :v
Would be better to forget this approach. I mean, or build a new one or show exactly how you are deciding lights turn off or not, you can even call the “thing to happen when lights goes off” from the script that randomly enable and disable lights, without the need of checking if all lights are on or off
The warn doesn’t work. It seems the previous lines are the problem. Ahhh I’m so tired I think I will change the each lights name to unique names and use if and
Scripting is tiring yeah. Choose what fits better for you 
Wait for @ico4n code, seems like its building the entire system to do what you need

]]

point out any mistakes if possible lol, i wrote this on VSC since i don’t have access to Studio at this moment
Tested out your code and it does seem to work. I added a little bit of code to it so that it is clear when all the lights are off. The updated code is found below (almost identical to Remiski’s original code)
-- script.lua
-- first, i would recommend you placing all the baseParts with the lights into a folder then name it whatever you want
local lightsFolder:Folder = game.Workspace.Lights --[[ replace "nil" with the path to the folder

]]
local probablity = 1 -- chance of all of the lights would turn off scaling up to 100
local duration = math.random(1, 7) -- random duration
local workings = {}
function index(t, va) -- for table.remove
for i, v in pairs(t) do
if v == va then
return i
end
end
return nil
end
for i, v in pairs(lightsFolder:GetChildren()) do
if v:IsA("BasePart") then
local light = v:FindFirstChildWhichIsA("SpotLight") -- replace SpotLight with any type of light if you're changing
if light and light.Enabled then
table.insert(workings, light)
end
end
end
task.spawn(function()
while true do
repeat
task.wait()
until #workings > 0 -- the code would stop working if there are no more lights in the folder
task.wait(duration)
local chosen = workings[math.random(1, #workings)]
local chances = math.random(1, 100)
if chosen then -- just in case if the object doesn't exist
chosen.Enabled = false
end
table.remove(workings, index(workings, chosen))
if chances <= probablity and #workings > 0 then -- if the chosen number is smaller than the given probablity
for i, v in pairs(workings) do
if v then
v.Enabled = false
end
table.remove(workings, index(workings, v))
end
-- insert a function here
end
if #workings == 0 then -- THIS DETECTS IT
warn("All lights are off")
end
end

Same, I tested it and works great!
The detail, I understood from your explanation and OPs too. That should be a loop that has a chance to turn off all lights at the same time, and I assume constantly turn them on again to continue with the loop, sometimes one or more lights, and sometimes all lights should be turned off… haha but idk

i’ve updated the code, adding a connection to automatically add another LightPart into the table once they’re parented into the folder with the print statement when all the lights are off too (@SeargentAUS)
mark this post as solution if it works

return i
end
end
return nil
end
function insertLight(part)
if part:IsA("BasePart") then
local light = v:FindFirstChildWhichIsA("SpotLight") -- replace SpotLight with any type of light if you're changing

table.insert(workings, light)

end

I tred using if and and for unknown reason it still doesn’t work. Idk what’s wrong with the script.
warn("This working")
if workspace.lamp.SurfaceLight.Enabled == false and workspace.lamp1.SurfaceLight.Enabled == false and workspace.lamp2.SurfaceLight.Enabled == false and workspace.lamp3.SurfaceLight.Enabled == false then
warn('working ag')
local cret = workspace.cret
cret:SetPrimaryPartCFrame(CFrame.new(12.129, 2.665, -44))
cret.sou:Play()
wait(10)
cret.sou:Stop()
cret.sou.SoundId = "rbxassetid://9069546509"
cret.sou.Volume = 2
cret.sou:Play()
wait(0.1)
cret.hed.BillboardGui.Enabled = true
wait(5)
cret.sou:Stop()
cret.sou.Volume = 1
cret.sou.SoundId = "rbxassetid://2184044761"
cret.hed.BillboardGui.Enabled = false
cret:SetPrimaryPartCFrame(CFrame.new(0, -5, 0))
end
The script stops at line 2 or 3. No errors.
In order for that to work, the if statement should be run everytime the lights changes, or at least in a constant loop. When are you running that code?
I insist that you should show the code you are using to turn on/off lights, thats when the “all lights turned off event” should happen. Not by trying to check when lights are off.
Can I use while true do with wait(1)?
