Theatrical smoke and fog, also known as special effect smoke, fog or haze, is a category of atmospheric effects used in the entertainment industry.The use of fogs can be found throughout motion picture and television productions, live theatre, concerts, at nightclubs and raves, amusement and theme parks and even in video arcades and similar venues.
Because of this, use of the fog lights when visibility is not seriously reduced is often prohibited in most jurisdictions; for example, in Australia, "The driver of a vehicle must not use any fog light fitted to the vehicle unless the driver is driving in fog, mist or under other atmospheric conditions that restrict visibility.

In volumetric lighting, the light cone emitted by a light source is modeled as a transparent object and considered as a container of a "volume". As a result, light has the capability to give the effect of passing through an actual three-dimensional aerosol (e.g. fog, dust, smoke, or steam) that is inside its volume, just like in the real world.
They can be used to help pilots and drivers steer their vehicles at night and in fog, or to detect warm objects against a cooler background. The wavelength of infrared that thermal imaging cameras detect is 3 to 12 μm and differs significantly from that of night vision, which operates in the visible light and near-infrared ranges (0.4 to 1.0 μm).
Red is the most used color on Japanese emergency vehicles. Japanese police use light bars mounted on a raised (mechanical) platform to make them more visible over congested streets. Rotating lights are most commonly used. But some newer vehicles have LED light bars installed. Vehicles with any other light color than red are security or engineers.
Unlike theatrical fog, which is typically intended to be dense and/or opaque, haze is generally very light and subtle. These properties allow a venue to be filled with haze prior to or during an event without creating an overtly distracting cloud. Haze typically has a substantially longer persistence ("hang time") than conventional theatrical fog.
A motorcycle misidentified as a padiddle is a foul that awards the offender's partner a double hit or kiss. Players can not use their own vehicle as a point. [citation needed] Fog lights do not count as a padiddle even if used as primary lights. There is no such thing as a double padiddle. [11] [13]
