How to get a massive light coming from the ground ?


I am currently working on some Cyberpunk scene and I saw something on the forum which I really would like to reproduce but really don’t know how.
Here is the topic:…berpunk-street

What I am talking about is the huge lights we can see in the background and coming from the ground (cf picture).

Can someone help doing something like this ? Where to start ? What component is it ? etc… Thanks !
