A proven light, with a classic, easy wipe design. Five LEDs face backwards in a transparent red case for an all-round glow. It runs for hundreds of hours in constant, flashing or ripple modes on the two AA batteries included.
The mounts supplied will fit most size seatposts. Make sure you tighten them though because we've had them shake loose and get lost before. Sealing is reasonable, the on/off button is big and battery replacement is tool free.
