If the car is an imported model then the tail lights surface can have their material changed in Lumion, increasing the Emissive of the Standard Material or Overbright for color values.
If the car is a Lumion Library Object, then you cannot change surface materials other than overall color, so lights need to be added. This is more suited to static views only.
The other option is to make and add a model so that the surface can be added near the tail lights and adjusted, as billy007nh has mentioned in reply your same question other topic:
Night RenderingFor just adding lights you can just add two spot lights, narrow the Cone Angle and point to the area of the tail lights. The dark (no Overbright) car works best as no light cast was noticeable so for the light colored car the spotlights needed adjusting inwards.
