NiteRider's Lightning Bug USB Combo lights are tiny, mount-almost-anywhere rechargeable safety lights that install without tools. The headlight has a bright, 100-lumen LED and high, low, daylight, and flashing modes. And in the rear, you'll be seen from up to a half mile away thanks to the taillight's bright 25-lumen LED with four modes (high, low, and two flashing patterns). Both lights easily mount to your bike with the included rubber straps. Plus, you can charge them both in under 3 hours from any USB port!
