I purchased the light set for safety when riding home on the streets at dusk/early night. The front light is more of a "to be seen" light, and not a "to see" light, though it is definitely bright enough to see larger, more notable road hazards in front of you with the light angled down (but small tire hazards could be missed). The tail light is perfect for my purpose and very visible in any of the flashing modes, both during the daytime, and especially as the sun goes down. Happy with the purchase, for its intended purpose.
This is one bright light. When the batteries were installed, I was looking at it when I turned it on. Bad. I was temporarily blinded.
The mounting is quite secure. No fear of the light falling from the bicycle.
Riding the Natchez Trace Parkway on a sunny day, I am often in the shadow of trees.
No doubt motorists see this light set to the random flashing pattern and know of my presence.
This light I can recommend as being able to save one's bacon on the road.
