Review on BrightRoad First Smart Bike Light Set - 80 Lumens Front & 40 Lumens Rear LED Lights, IPX6 Waterproof With Auto On/Off Sensor And Built-In Reflectors. by Josh Hamler

Having only had these for about a week, I will give my initial impressions. From a full charge. I used the lights on an intermittent basis for around 20 hours before recharge and the low battery indicators had not come on. The taillight is brought enough to be seen in any conditions that I would ride a bike on the street in. The headlight doesn't have a focused beam and would be virtually impossible to aim, which is not a problem as it is designed to help you be seen and not so much to help you see. If you are riding at night, carry another headlight work a focused beam. I use a rear cargo basket for commuting and like the clip on the taillight (headlight also has a clip) as it allows me to put the strap on the seat post and attach the light there when the basket is off (seldom) or clip it directly to the basket. All in all, they seem well thought out and practical.
