    I have had a lot of people tell they do not see tail lights on a car this bright. While others just want to know what it is so they can get one. I only use Serfas lights quality and service!!

    Nice brightness and flash options. However, they have made the adjustable bracket the light attaches to SPRING LOADED (i.e., you cannot totally tighten it). So, although the rotational adjustment has teeth to help keep it in place, any severe bump causes the orientation to shift, due to the weight of the light itself. This is especially bad if the light is mounted on a vertical tube – the light orientation can rotate up or down, depending upon the harshness of the bump encountered. Mine is mounted on a horizontal tube, and it shifts left and right.

    Get rid of the spring loading!!!

    I like the brightness and how the light is much brighter viewed in direct and less from side but still visible. Battery life good. Mount excellent.

    Excellent product, well worth the price for extreme brightness, visibility and safety. Mount is perfect.
