Teardrop Light 15
Teardrop Light 15 : Scientific Research: (1) Perception: A study at Loughborough University in the United Kingdom showed that strobe lighting conveyed a greater sense of urgency to other road users, with the faster the flash the greater urgency, potentially helping to speed the emergency vehicle through traffic. It also concluded that factors such as flash pattern were important, with simultaneously flashing beacons attracting attention far quicker than alternately flashing versions, although this did increase discomfort glare. Unsurprisingly, attention was gained far quicker the higher the intensity of the light was, and the more beacons were present. This same study compared different light colors for glare and detection time under both daylight and night conditions. While red and blue both compared favorably with amber for glare under various conditions, some contradictory findings were observed for detection time. When all colors were held at equal intensity, amber had the poorest detection time both daytime and night. But when the light source was held at constant intensity, the amber filters, which generally let the most light through, had the best detection time
