I can't use 2D lights

For some reason my 2D lights in unity are grayed out, there are some answers regarding this problem but i can’t seem to understand them, help would be appreciated

Okay, i looked into it and i managed to solve the problem, i had to create a renderer by going to Assets > Create > Rendering > Universal Render Pipeline > Pipeline Asset and then i went to Edit > Project Settings > Graphics and assigned the Universal Render Pipeline Asset.asset to the Scriptable Render Pipeline Settings, after i assigned it, i made a 2D renderer by going to Assets > Create > Rendering > Universal Render Pipeline > 2D Renderer and then i assigned the 2D renderer in the Universal Render Pipeline Asset.asset and then it should work, if you still don’t understand then you can go and check out this video : 2D Lights and Shadows in Unity 2019!

This issue I’m facing now is, with URP available, I can’t get rid of the (experimental) part of the 2d lights, as well as some of the render pipeline feature. This is preventing me from using the new post processing effects.
