How would I loop Loop/Repeat?

Redlight.Enabled = true
wait(3)
Redlight.Enabled = false
wait(3)

I want it to repeat it self, so it always blinks the redlight. What is the loop code?

while wait(3)do
	Redlight.Enabled=not Redlight.Enabled
end

Switches Redlight.Enabled every 3 seconds

while true do
Redlight.Enabled = true
wait(3)
Redlight.Enabled = false
wait(3) -- I added this because you don't want it to loop instantly back to on. Needs some smoothness, y'know?
end

1 Redlight.Enabled = true 2 wait(3) 3 Redlight.Enabled = true 4 wait(3)

It will repeat that way.

while true do
-- Whatever
end
