The current status of auotomobile running lights.
The results of a number of studies of the use of lights to make a vehicle more visible have shown that they are effective. Accident studies have shown a drop in accidents from 7 to 59%. Only one of the studies used properly designed and positioned presence and signal lights and yielded 59% fewer accidents. It is concluded that a 50% or greater reduction of accidents is probable when using a high mounted 360 degrees visibility signal and running light combination.
