Very bright, nice beam pattern. The beam has good spread but a little less depth so lights with a more focused spotlight pattern are better for higher road speeds. Light weight, small size, very good quick mounting system. Unit pivots on the mount which is very nice. Amber side lights are a good feature.
DOES NOT FLASH - it only pulses slightly on the low setting which is perfect for keeping the road visible on that setting and a total total fail for use as a warning light, for example in daytime or on a running path. If you need a true flash mode, this will not work. If not, it is a great little light.
