That said you need to adjust the angle of the light so it lights the road and doesnt totally blind a person or vehicle that is on coming but its great for occasional use, Its perfect for my son who ride their bike home from a friends home just down the street at night.

They certainly were splashed a lot and worked flawlessly. At the back MET520 written with white big fonts on the black shoes.
