Ideal for urban riding and commuting on lit and unlit surfaces, touring and training. Excellent LED performance and efficiency. The Cyo T has a nice beam, improved near-field road illumination and even more distribution of light from near to far on the road, and a revised switch. Long, wide pattern illuminates surface at moderate and higher speeds, sharp upper edge limits glare from oncoming traffic. Light is also visible from the side for increased visibility. The Cyo T Plus has all the same features as the standard Cyo. The Cyo T differs in that while in 'Senso mode' and riding in daylight, the Daytime Running Lights are at full brightness. At dusk, the headlight will automatically switch over to nighttime mode and the Daytime LEDs will dim down so the road can be fully illuminated by the main LED which runs at full brightness.
