Planet Bike Superflash Rear Light $24.99Talk about bright! The Planet Bike Superflash will knock your socks of with its super bright strobe setting. With a 100 hour run-time, the Superflash is the perfect light to mount on your bike. The light tubes are made of unbreakable thermoplastic, so there's no glass to break. In fact, the DLG is suitable for off-road riding. The bright neon glow lasts for about 2.5 hours, after which you bring the rechargeable, Nickel-Metal Hydride battery inside for charging. The DLG's light tubes attach to your bicycle's downtube and to the chainstay with removable mounting clips. No zip ties are required. Charger and full mounting kit included. The DLG only adds a pound to your bike.
The DLG is available in two models: single tube and dual tube. They both come with the same high-quality rechargeable battery. The single tube model has a simple installation and twice the 'glow time', but half the light output
