They do exactly what I wanted them to, strobe on front and rear to get cars attention during the day. A cheap solution for possible saving your life
The front light is bright but does not really focus on the terrain before you and shines in a wide beam that sort of blinds you. The tail light is good especially in flash mode. Both are difficult to turn on and off at times, having to press the center of the light in the exact spot in order for it to function while actually riding is difficult. I would not buy them again.
