How do i disable a material changing script using another click detector in a different part?

I just started scripting last week and im trying to make a brick thats flashing neon red turn to "Institutional white" and stop flashing after the click detector is clicked.

Here is the click detector script. Its not in the same group as the neon flashing red brick.

local cd = script.Parent
local light = game.Workspace.WarningLight
local Button = game.Workspace.Button.Buttn
cd.MouseHoverEnter:Connect(function()
    light.Transparency = 0.3
    Button.BrickColor = BrickColor.new ("Bright red")
end)
cd.MouseHoverLeave:Connect(function()
    light.Transparency = 0
    Button.BrickColor = BrickColor.new ("Institutional white")
end)
cd.MouseClick:Connect(function()
    light.BrickColor = BrickColor.new ("Institutional white")
end)

Here is the flashing red neon brick script

local part = script.Parent
while true do
    wait(2)
    part.Material = Enum.Material.SmoothPlastic
    wait(2)
    part.Material = Enum.Material.Neon
end
