PointLight

This example creates a new anchored BasePart named Part at the position {0, 0, 0}.

It then creates a new point light with brightness of 1, Color3 color of {255/255, 255/255, 255/255} (white) and range of 16 studs. The point light's parent is set to the BasePart we created. To view the light, navigate to the part at {0, 0, 0} or move the Part created to a location visible to the player.

Please note that the properties of the created point light can easily be changed by modifying the property values in the code sample below. Additionally, if you have an existing point light, you can also create a similar script that modifies that light instead of creating a new BasePart and light.

local part = Instance.new("Part")
part.Anchored = true
part.Position = Vector3.new(0, 0, 0)
part.Parent = workspace

local light = Instance.new("PointLight")
light.Color = Color3.new(1, 1, 1)
light.Brightness = 1
light.Range = 16
light.Parent = part
