Larock Bike Tail Light USB Rechargeable Bicycle Led Light Amazingly Bright LED Rear Bike Warning Light Larock LED Light is an Bike Accessories that fits on any Bicycles and Helmet

**update**Well don't bother with this version. I thought the red silicon case would keep it dry in the rain but after a slight misting of rain during my ride, the light shorted out. The red casing is not sealed and does nothing to protect it from the elements. There's pretty much the same light, minus the red casing that you can get for half the price. Don't waste your time with this one, it'll only last you till the first rain you get caught in.Another issue I had is there is no indication for when the battery is low, it just turns off on your ride. Otherwise this light will turn on, even when it barely has a charge, and stay on long enough for me to get riding and then turn off during my ride. Twice I've turned on my light but by the end of my short ride the light was off.Also they use a ridiculous amount of plastic to package this light, where a simple cardboard box would suffice.

Slow to recharge. Shuts itself off when charge is low. For safety, I need the taillights to stay on until I turn them off or battery is 100% discharged. I should not be able to turn it back on when I finish my ride.I need the battery to be good for at least two hours on brightest setting.

Loved the style, but the light did not hold a charge for more than a day, which I consider unacceptable.

Very bright light, nice choice of strobe fx, can't miss it.

I've been quite happy with this unit. I have it attached to the back of my helmet, and it is a simple thing to reach back and activate the switch.

Worked great for about 4 weeks, then it stopped. No response from Larock when I tried to contact them to replace or return it.

Worked great for a couple of days until the battery died, now it won't charge. Total waste of money.

How in the world did we live without USB cords before? This bike tail light is such an awesome idea! No more buying batteries! Just plug it into a computer (or a USB outlet plug) for 2 hours and you're set to go. The tail light is good for up to 3 hours and because it's an LED light, you don't have to worry about replacing a lightbulb either. Its silicone coating makes it water resistant in case you're out in the rain. You can set it to dim, medium or high as well as 3 different modes of flashing. The strap on the light allows you to attach it to anywhere on your bike, helmet, or even yourself if you are running/walking at night. Awesome light!I received this product at a discount in exchange for testing and an honest review. I stand by my review and do not give discounted products great reviews if I would not personally recommend them. I count on honest reviews as much as you do when making purchases! If you've found my review to be helpful, please give me a thumbs up because it helps me too. :)
