This mod adds another feature from GTA III, where during sirens from police/firefighter vehicles, there was a swirling light from the siren lights on the ground. The intensity/color depends on the coronas. There is also a light from police bike sirens. There is a .ini file with the following settings: Brightness division factor of the light sources. The higher the value, the less brightness of the light. Should the light appear on the bikes, and what texture of light to use.
