The Helios 2.3 flashing taillight from M-Wave is an easy addition to your ride. The two half-watt LEDs shine brightly through the red lenses, and operate with three different functions. You can install and remove the light without tools via the clip-on bracket, and the light can be turned 90 degrees to suit your style and other items you may be carrying on your bike. Be safe, be seen...M-Wave.
