Hello Lee10,
 
I actually encountered the same issue when I was using version 0.3, anyway for me this issue was related to the mod VisualV and using ELS models cars.
The only way I found to deal with this was using "Brighter Emergency Lights (RADIANCE V)" instead of VisualV. Note that I used this mod because the lights were not bright at all !
So my recommandation will be to remove your mod if not needed and if you use it because of the ELS lights then try the mod I've shared above.
