Bug Light2D instantiated at runtime not lighting anything

I'm working on a 2D scene using lit sprites - any Light2D objects into the scene at launch render fine. However I'm trying to add a Light2D (a spotlight to be specific) programmatically and it doesn't light anything.

The setup is very simple to reproduce - just make a prefab that has a Light2D Spotlight on it and then instantiate it via a script and it will not light any lit sprites.

Using Unity 2021.3.19f1
URP 12.1.0

Any advice is appreciated! I feel stuck.

 

Got it I'm just a dummy - I was rotating the game object incorrectly which caused the light to go crazy - was basically looking at the backface of it.
