I am using unity 2019.2. I was wondering if it was possible to attach a halo component to my particle so it spawns on each mesh. I know you can add a light, but it doesn’t seem like you can add a halo?

Correct - you can’t spawn a halo on every particle.
Perhaps a post-processing effect could give you something close to what you want.
