An excellent dynamo light in a very small package!
Only 5 cm long and weighing only 70g, The Eyc is plenty bright for spirited riding on dark roads.
50 lux and great IQ2 optics gives you good visibility at a distance, but also excellent near-field illumination of the road ahead.
The Eyc N Plus has a simple on/off switch and a stand light that shines when you stop (like at a stop light). It glows for several minutes and is a significant safety feature.
