    en.wikipedia.org/wiki/Automotive_lighting

    Cars in the US only have red tail lights, and no blue lights; a vehicle displaying a red (forward-facing) light (flashing or not) coming towards a driver, or from behind the driver (in rearview mirror) indicates that an official emergency vehicle is coming, requiring the driver to yield, pull off to the side of the road, or otherwise get out of ...

  3. Temporal light artefacts - Wikipedia

    en.wikipedia.org/wiki/Temporal_light_artefacts

    Temporal light artefacts (TLAs) are undesired effects in the visual perception of a human observer induced by temporal light modulations. Two well-known examples of such unwanted effects are flicker and stroboscopic effect. Flicker is a directly visible light modulation at relatively low frequencies (< 80 Hz) and small intensity modulation levels.

  4. Fluorescent lamps and health - Wikipedia

    en.wikipedia.org/wiki/Fluorescent_lamps_and_health

    Fluorescent lamps with magnetic ballasts flicker at a normally unnoticeable frequency of 100 or 120 Hz (twice of the utility frequency; the lamp is lit on both the positive and negative half-wave of a cycle). This flickering can cause problems for some individuals with light sensitivity [1] and are

    The Jeep market was also a market in which the Big Three had no presence, and therefore there was no competition. American Motors gained the iconic Jeep brand of light trucks and SUVs, as well as Kaiser-Jeep's government contracts – notably the M151 line of military Jeeps and the DJ-Series postal Jeeps. American Motors also expanded its ...

  7. Flicker (light) - Wikipedia

    en.wikipedia.org/wiki/Flicker_(light)

    In visual perception, flicker is a human-visible change in luminance of an illuminated surface or light source which can be due to fluctuations of the light source itself, or due to external causes such as due to rapid fluctuations in the voltage of the power supply (power-line flicker) or incompatibility with an external dimmer.

  8. Hydrargyrum medium-arc iodide lamp - Wikipedia

    en.wikipedia.org/wiki/Hydrargyrum_medium-arc...

    The problem of flickering exists only when using the bulb in combination with magnetic ballast (electronic ballasts produce flicker-free light). HMI bulbs (running with magnetic ballast) present an inherent problem of possibly producing light on film or video with a noticeable flicker. This is caused by the method by which the unit produces light.
