Luminosity:
Front light - The light is clearly described as a supplementary light, and so it should also be evaluated. It may even be enough to small trips with little street lighting to cover. For longer trips, I would also always use a real bike light.
Taillight - The taillight could remain in continuous use since the red light is clearly visible and is not used to illuminate a road.
Fixed on a bike:
Front light - a prerequisite for Lucetta is an underground metal. It does not really matter whether the surface is a round bar or a plate surface. The light keeps very good at both. Small downside to the bar (I myself have the backlight always on the handlebar) - it must be readjusted sometimes when you go over a few bumps. But I find not so bad.
Rear light - the rear light keeps me on the frame under the saddle without problems and without slipping. Ideal place for the light! No complaints.
Quality:
I read one time or another, that the different "Blink variants" are not working properly. I can not confirm now. I have the light now been a few months in operation (even in light rain) and had no change battery or had problems with the technology. So here is a clear plus.
Anyone who is looking for a little extra light on the bike, the evening on the way to the bar for training or home but still want to share the great lamps, is well advised with Lucetta!
