local light = script.Parent.PointLight

while true do
    light.Brightness = 2
    wait(.1)
    light.Brightness = 2.2
    wait(.1)
    light.Brightness = 2.4
    wait(.1)
    light.Brightness = 2.6
    wait(.1)
    light.Brightness = 2.8

Use tweening.

A) It'll produce smoother results

B) It can be reversed

C) Way more concise

local tween_service = game:GetService("TweenService")

local light = script.Parent.PointLight

local tween_info = TweenInfo.new(
    1,   -- time 
    Enum.EasingStyle.Linear, -- easingstyle
    Enum.EasingDirection.Out, -- easingdirection
    100, -- repeats (should probably go higher for infinite loop)
    true -- the magic parameter to make it reverse
)  -- you can tweak these settings of course (see wiki links below for help)


local light_tween = tween_service:Create(light, tween_info, {Brightness = 5})
light_tween:Play()

TweenService TweenInfo

Before I discovered this, I used for loops. I still am not quite familiar with the tween syntax. User#24228 0 — 4y

TweenService:Create is a very simple function really. Look through the Wiki page, but the example program at the bottom might be most helpful to you: https://developer.roblox.com/en-us/api-reference/function/TweenService/Create LukeSmasher 619 — 4y

Well you could just make a loop that changes the brightness by 0.2 each time.

local light = script.Parent.PointLight

while true do
    wait(0.001)
    local light = script.Parent.PointLight

-------------------------------------------------------------------

    local currentBrightness = light.Brightness
    wait(0.1)
    currentBrightness = currentBrightness + 0.2
end

If this solved your question please accept this answer.

that wouldn't work because it would just continually increase the brightness and not decrease it at any given point SKOSHILOKI 67 — 4y

while wait(0.1) do
    for i = 2,5,0.2 do
        script.Parent.PointLight.Brightness = i
        wait(0.1)
    end
    for i = 5,2,-0.2 do
        script.Parent.PointLight.Brightness = i
        wait(0.1)
    end
end
