Need help in rotating the magic attack

I didn’t understand how to make LightBeam3 and LightBeam4 face the other side, can somebody help?

game.ReplicatedStorage.RemoteEvent.OnServerEvent:Connect(function(Player, Debounce)
	if Player.UserId == 1018441530 then
    local Character = Player.Character or Player.CharacterAdded:wait()
    Debounce = true
    local LightBeam = Instance.new("Part")
    LightBeam.Name = "LightBeam"
    LightBeam.Size = Vector3.new(3,3,3)
    LightBeam.Shape = Enum.PartType.Cylinder
    LightBeam.Material = Enum.Material.Neon
    LightBeam.BrickColor = BrickColor.new("Really red")
    LightBeam.CanCollide = false
    LightBeam.Parent = Character
    LightBeam.CFrame = Character:GetPrimaryPartCFrame()*CFrame.new(0,0,-10)
    LightBeam.Anchored = true
    local LightBeam2 = Instance.new("Part")
    LightBeam2.Name = "LightBeam2"
    LightBeam2.Size = Vector3.new(3,3,3)
    LightBeam2.Shape = Enum.PartType.Cylinder
    LightBeam2.Material = Enum.Material.Neon
    LightBeam2.BrickColor = BrickColor.new("Really red")
    LightBeam2.CanCollide = false
    LightBeam2.Parent = Character
    LightBeam2.CFrame = Character:GetPrimaryPartCFrame()*CFrame.new(0,0,10)
    LightBeam2.Anchored = true
    local LightBeam3 = Instance.new("Part")
    LightBeam3.Name = "LightBeam"
    LightBeam3.Size = Vector3.new(3,3,3)
    LightBeam3.Shape = Enum.PartType.Cylinder
    LightBeam3.Material = Enum.Material.Neon
    LightBeam3.BrickColor = BrickColor.new("Really red")
    LightBeam3.CanCollide = false
    LightBeam3.Parent = Character
    LightBeam3.CFrame = Character:GetPrimaryPartCFrame()*CFrame.new(-10,0,0)
    LightBeam3.Anchored = true
    local LightBeam4 = Instance.new("Part")
    LightBeam4.Name = "LightBeam2"
    LightBeam4.Size = Vector3.new(3,3,3)
    LightBeam4.Shape = Enum.PartType.Cylinder
    LightBeam4.Material = Enum.Material.Neon
    LightBeam4.BrickColor = BrickColor.new("Really red")
    LightBeam4.CanCollide = false
    LightBeam4.Parent = Character
    LightBeam4.CFrame = Character:GetPrimaryPartCFrame()*CFrame.new(10,0,0)
    LightBeam4.Anchored = true
    wait(.2)
    LightBeam.Size = Vector3.new(500,10,500)
    LightBeam2.Size = Vector3.new(500,10,500)
    LightBeam3.Size = Vector3.new(500,10,500)
    LightBeam4.Size = Vector3.new(500,10,500)
    LightBeam.Touched:Connect(touched)
    LightBeam2.Touched:Connect(touched)
    LightBeam3.Touched:Connect(touched)
    LightBeam4.Touched:Connect(touched)
    wait(2)
    LightBeam:Destroy()
    LightBeam2:Destroy()
    LightBeam3:Destroy()
    LightBeam4:Destroy()
    end
end)

function touched(hit)
	if hit.Parent.Humanoid then
		hit.Parent.Humanoid.Health = hit.Parent.Humanoid.Health - 12
	end
end

EDIT:
I’m trying to make it rotate by player direction, but I need for LightBeam3 and LightBeam4 face the other side but not the same as LightBeam and LightBeam2

you can rotate a CFrame by using CFrame.Angles.

Part.CFrame = Part.CFrame * CFrame.Angles(0,math.rad(90),0) --This will rotate the part by 90 degrees
