Wait(n) not working in while true do loop (lua ROBLOX)

Hello Everyone
I am trying to make the lights on a police car keep flashing, but the while loop I am using does not work.

The Output shows that the wait loops does not function, and I have used print statements to see where the issue was. Please help

What I have tried:

local blue = script.Parent.Blue
local red = script.Parent.Red

--Flashing lights
while true do
	red.Material = "SmoothPlastic"
	red.SpotLight.Brightness = 1
	blue.Material = "Neon"
	blue.SpotLight.Brightness = 3
	print('Blue Lights Activated')
	wait(2)
	print('Waiting Procedure')
	wait(0.1)
	red.Material = "Neon"
	red.SpotLight.Brightness = 3
	blue.Material = "SmoothPlastic"
	blue.SpotLight.Brightness = 1
	print('Red Lights Activated')
end

local blue = script.Parent.Blue
local red = script.Parent.Red

--Flashing lights
for i=1, 1000 do
	red.Material = "SmoothPlastic"
	red.SpotLight.Brightness = 1
	blue.Material = "Neon"
	blue.SpotLight.Brightness = 3
	print('Blue Lights Activated')
	wait(2)
	print('Waiting Procedure')
	wait(0.1)
	red.Material = "Neon"
	red.SpotLight.Brightness = 3
	blue.Material = "SmoothPlastic"
	blue.SpotLight.Brightness = 1
	print('Red Lights Activated')
end
