Excellent product !!!!!!!!!!!

Vary bright light and it has very good light patterns only had for a few weeks

Bracket wouldn't completely tighten around the seat stem. I just added another piece of rubber and it's fine

I rushed my purchase of this and thought the color choice of blue and red was the color of the plastic body to the light. I opted for blue to match my blue bike. But the blue color actually describes the light itself. So, I have a blue flashing light - that I can't use. Blue lights like this are reserved for the police department. But I liked the construction and solid feel of the light, so I bought another one - this time with a red light!
