Riding your bike safely at night is all about being seen - so the last thing you want to worry about is a dying battery or a dead bulb. Worry no more. The Power Plus LED Bike Light puts the brilliance of LEDs to perfect use in a new "world"s first" wind-up bike light. This complete bike light set comes with a 3-White LED headlight and a 3-Red LED taillight. You can set both lights for either a constant light a flashing light to call more attention to yourself.The rechargeable battery for both lights is in the headlight - and so, when the lights start to dim, you only have to wind-up the headlight. The taillight connects by a slim cable to the headlight, so you don"t have to worry about winding it up as well. All mounting hardware is included, so it"s easy to get the lights connected to your bike and hit the road.The headlight is bright enough to give you plenty of light in the dark, and can also be removed from its mount and used as an independent flashlight. The red taillight only works when connected to the headlight.One minute of winding gives you 8 minutes of bright light for headlight and taillight combined, or 60 minutes of flashing light.When fully charged, you"ll get up to 50 minutes of light from headlight and taillight.You can also use the headlight to recharge your cell phone. There is a DC jack on the side, and the light comes with a standard cable for Nokia phones (except N-types).
