Serfas' Thunderbolt Headlight delivers 90 lumens in an extremely versatile, USB-rechargeable package. Attach the water-resistant silicone body nearly anywhere on your bike, and use the high, low, or two flash modes to make sure cars, cyclists and pedestrians can see you at night. At just 50 grams, you won't even notice it's on your bike — but others will!
With 250 lumens, Serfas' TSL-S250 Headlight commands attention. Five different modes are powered by a long-lasting, rechargeable Lithium-ion battery that is built into the light body. With the included USB cable, you can conveniently recharge your light right at your computer. Plus, the battery is user-replaceable. It also includes a quick-release handlebar mount.
