Abstract
This study deals with the conspicuity of flashing light signals of different frequencies, durations, and contrasts. It was planned to obtain information about the effects of these variables. The data show that at either high contrast or frequency, a change of the other factors does not produce a significant effect. At low contrast, however, conspicuity increases as flash frequency increases; and with low frequencies, conspicuity increases as brightness contrast increases.Keywords
