How to create a light array

I’m trying to create a blueprint with which I can set the number of lights I want to add with a variable and adjust the distance between the lights. Should be really simple I figure, but I just can’t get it to work.

Bit more info. Grid or sphere or line or what?

A simple line or grid of point lights
Context: I have a aerial shot of a city to which I want to add streetlights. Simple pointlights will do. Instead of manually adding hundreds of pointlights, I figured I’d be better of creating a blueprint to do this

You are a hero, ty so much!
Only thing I can’t get to work is the relative transform. I don’t see those options in the add point light node…

But this works, no? Before connecting, you can right-click on the pin, and choose ‘split’.
