I've been able to test the LICHT24 system, now (Cyo R with daytime running lights). Though I'm unable to compare the light with the "non-LICHT24" series, I'll still comment directly on what I did try. I quite like the product. The beam (i.e., the main driving light) is very bright, and burns at maximum intensity at speeds of just a few miles an hour; it doesn't flicker at low velocity, either, as did my halogen head-lamp. The four L.E.D.s below the main light, too, are very bright, but seemingly not so much so they would be an annoyance to oncoming traffic or pedestrians.

The light features three settings: 1) off, 2) senso, and 3) day. When off, everything is totally unlit; in day mode, the four L.E.D.s are bright, and the main head-lamp is slightly dimmed (rather than be white, it bears a mild blue/purple flavor); set to senso, the item automatically switches between "day" and "night" modes (oddly, one cannot manually select "night"). When it switches to "night," the headlamp becomes brighter (the color is an attractive white) and the four L.E.D.s somewhat dim.

Overall, I rather like this product. The additional option to manually select night mode might have been welcome, but, as it is, I'm perfectly happy leaving the light on its "senso" setting, which appears to be quite reliable.
