Product Details

Serfas Thunderbolt Headlight

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!
