Why my light, color, and enabled doesn't work in this script?

So, I've been working on my horror game. And i don't know, why but this is not working.

local LightTrigger = game.Workspace.LightTrigger

LightTrigger.Touched:Connect(function(hit)
	if hit and hit.LightTrigger:FindFirstChild("Humanoid") then
		script.Parent.Parent.BrickColor = BrickColor.new(255,255,255)
		script.Parent.Enabled = true
		script.Parent.Parent.SurfaceLight.Enabled = true
			LightTrigger:Destroy()

	end
end)

assuming the script is in the trigger and the part you want to be changed is the parent of the trigger and both are parts, you could do

script.Parent.Touched:Connect(function(hit)
	local character = hit.Parent
	if character:FindFirstChild'Humanoid' then
		local part = script.Parent.Parent
		--         script.Parent.Enabled = true (dont think that is a thing)
		part.BrickColor = BrickColor.new('color')
		part.SurfaceLight.Enabled = true -- make sure theres a surface light in the part
		script.Parent:Destroy()
	else
		print'not player'
	end
end)
