'Particle System' Lights do not support Experimental 2D Lights



How to reproduce:
1. Open attached project "" and scene "SampleScene"
2. In Hierarchy window, create any 2D light (right-click -> Light -> 2D -> * Light 2D (experimental) )
3. In Hierarchy window, select Particle System object
4. In Inspector, Enable 'Lights' sub-component
5. Try to drag the created 2D light into the Lights -> Light field

Expected result: the 2D light is attached to the Light field
Actual result: the 2D light is not attached to the Light field

Reproducible with: 2019.4.3f1, 2020.1.0b15, 2020.2.0a17
Could not test with: 2018.4 (2D Render Pipeline was not yet implemented/released)

    Resolution Note:

    Not possible to support this because 2D lights are MonoBehaviours in a package and the ParticleSystem has no way to handle them. At best we would need to just spawn GameObjects/Prefabs which is something a user can do with a script and would have no benefit being a ParticleSystem feature. We avoided this when we added the Lights module for performance reasons as we don't want the overhead of many GameObjects for simple lights however with 2D lights this is unavoidable.

    More info here including a script to do it:
