How do I change the direction of a PointLight?

You really can’t change of the direction of a PointLight as it only depends on the Range and Brightness overall, my guess is that you’re talking about SurfaceLight and SpotLight, PointLight is never used for surface and just a circular radius of an instance.
^ You could rotate it but it doesn’t do anything pretty much.
In order to do so, you can go to the properties with any of them and click on the property section Tab and then change it to any direction such as Back or Left, that’s how you change the direction of a PointLight.
Image of where you can find it in the properties tab:

Okay thank you. I still cant figure out how to do something like this with the lighting:
Do you have any ideas?
That’s not really possible with the way roblox’s lighting works. Try making a decal like this:
With whatever color you want, it will give the same-ish effect

You can create this by thinking outside the box. To create this, I’d suggest making it in blender than importing into studio. You would need to make the shape then select the vertices around the edges you want to light up in neon.
Like this:
Then separate the side and bottom faces by pressing “P” and clicking “selection” on the menu that pops up. Next, Use the “Extrude Region” button found under “tools” on the left side then press “ctrl + F” and click “flip normals” This will make the model double faced so you have a face facing inwards and outwards. You may need to resize it slightly before flipping the normals.
Model should be 2 parts looking like this now:
Move the model into studio and give the main glass part the “force field” material while giving the edge model a “neon” material.
It’ll then look like this:
You can place a light inside to give it more effect if you with as well. This looks best in higher graphics by the way. Hope this helps. 
Try using the relatively new force field material, it does this kind of stuff if you put parts at the edges of the force field or something.
