Randomized rotation that target a certain part

[ImaAetherangel (Aether)]

1. What do you want to achieve?

• So i make a lighting bold module that uses Random.new() to make the rotation. But i want make the rotation targetting a certain part

• Here Is My Module Script

local module = {}

function module.Make(Size:Vector3,Attachment:Attachment,MaxRot:number,FadeTime:number)
	local light = {}
	local ins = Instance.new('Part')
	ins.Parent = workspace.ex
	ins.Size = Size
	ins.Material = Enum.Material.Neon
	ins.Color = Color3.fromRGB(255,255,0)
	ins.CFrame = Attachment.WorldCFrame
	table.insert(light,ins)
	
	local lastchild = nil
	for i=1,20 do
		if i == 1 then
			local child = Instance.new('Part')
			child.Parent = workspace.ex
			child.Size = Size
			child.Material = Enum.Material.Neon
			child.Color = Color3.fromRGB(255,255,0)
			table.insert(light,child)
			
			local newpivot = CFrame.new((ins.CFrame:ToWorldSpace(CFrame.new(ins.Size.X/2,0,0))).Position) 
			local offset = newpivot:toObjectSpace(child.CFrame) 
			newpivot = newpivot * CFrame.Angles(0, math.rad(Random.new():NextInteger(-MaxRot,MaxRot)), 0) 
			child.CFrame = newpivot * offset * ins.CFrame:ToWorldSpace(CFrame.new(ins.Size.X,0,0))
			lastchild = child
		else
			local child = Instance.new('Part')
			child.Parent = workspace.ex
			child.Size = Size
			child.Material = Enum.Material.Neon
			child.Color = Color3.fromRGB(255,255,0)
			table.insert(light,child)
			
			local newpivot = CFrame.new((lastchild.CFrame:ToWorldSpace(CFrame.new(lastchild.Size.X/2,0,0)).Position)) 
			local offset = newpivot:toObjectSpace(child.CFrame) 
			newpivot = newpivot * CFrame.Angles(0, math.rad(Random.new():NextInteger(-MaxRot,MaxRot)), 0) 
			child.CFrame = newpivot * offset * lastchild.CFrame:ToWorldSpace(CFrame.new(lastchild.Size.X,0,0))
			lastchild = child
		end
	end
	task.wait(FadeTime)
	for _n, destroy in ipairs(light) do
		spawn(function()
			local t = game:GetService('TweenService'):Create(destroy,TweenInfo.new(.3,Enum.EasingStyle.Linear),{Transparency = 1})
			t:Play() t.Completed:Wait()
			destroy:Destroy()
		end)
		task.wait()
	end
end

return module

What i mean targetting/aiming is like this:

I want the part that makes the lightning is targetting the next part shown on the video. thanks

Why reinvent the wheel when there are many libraries out there for this? Some popular examples include Lighting Beams and ElectricArc. Also if you want to make a simple lighting effect you can figure out how the semi-randomized angles of each lighting part should act from this post.
