Real time rendering translucent plastic?

Hello, I've been trying to achieve a similar effect to a light being inside in a translucent plastic housing like found on Halloween and Christmas light decorations. 

I've tried placing omni point lights and emissive objects inside a SSS material object but they only become a light gradient across the object's surface.
Has anyone real-time rendered translucent plastic before or has a trick solution for a similar effect in Marmoset?

I've also tried using refraction transparency, which does give me the center hotspot I'm looking for, but no longer looks plastic. Instead with refraction on it looks glass or gel like.

    The easiest way to do this is probably to use an emissive map. That way you can customize it to have any falloff and color you like, and you won't need to place a light for each bulb. You can create a translucency map for a more dynamic effect as well.

    Thanks for the response!
    I have thought about using an emissive map on the plastic but the issue with a spherical object like these, is it only looks good from one angle. 
    and with a map there is no way to have that light source hot spot to always be centered. 
    In the image below from the video, the 3 at the bottom are decent, but the 2 to the left look off.
