Abstract

This paper reviews some of the material facts on flashing lights as signalling devices. The requirements of the used lamps are discussed to determine the effectiveness of various lamp parameters, including rate, duration, shape of flash, on-off ratio, background and position in field of view. The paper concludes with descriptions of two flashing direction indicator lamps and some off-vehicle flashing lights.
