How to make "Beam of light"?

Thank you for the reply!

Basically, I am using this module:
[Effect] v1.1 Lightning Beams: Seamless, smooth and procedurally animated with beam-like properties - Resources / Community Resources - DevForum | Roblox

To make lightning beams between 2 parts. But it doesn’t emit light. So, I am trying to make a light source along the lightning to do that.
