EverLightFX 2-Pack USB Rechargeable LED Safety Light Clip-On Strobe Light

617 HOURS PER CHARGE: The built-in 600mAh rechargeable battery provides 6 to 17 hours of runtime depending on the lighting mode. Recharge in about 1.5 hours from a USB port, power bank, laptop, car charger or wall adapter using the 2 included charging cables.
CLIP ON OR STRAP ON WEAR IT YOUR WAY: Use the built-in clip on belts, pockets, jackets, running gear, reflective vests or backpacks. Short straps secure the lights to bike frames, seat posts, pet collars and leashes; long straps fit around arms, wrists, ankles and calves.
RUNNING, DOG WALKING, STROLLER & BIKE LIGHTS: Use EverLightFX as running lights for runners and joggers, walking lights, dog collar lights, stroller lights, blinking warning lights or rear bike tail lights. Also useful for hiking, camping, kayaking and other outdoor activities.
ACTIVE VISIBILITY FOR LOW-LIGHT CONDITIONS: Unlike reflective gear that depends on an outside light source, these LED safety lights emit their own light to help make you easier to see. Clip them to reflective gear, clothing, backpacks or pet gear for added visibility at night, dawn or dusk.
LIGHTWEIGHT, WATER RESISTANT 2-PACK: Each IPX4 water-resistant polycarbonate light weighs about 1 oz and handles sweat, splashes and light rain. Includes 2 USB rechargeable safety lights, 2 charging cables, 2 short fastening straps and 2 long fastening straps.
