Review on DAWAY A08 Bike Tire Valve Stem Light - LED Waterproof Bicycle Wheel Lights for Cool and Safe Night Rides - 1 Pack/2 Pack by Andres Black

Now I only have one of these on the back wheel but soon I will be moving south which means the nights are getting warmer and shorter. Days in summer so I'll ride more at night. I will be buying another one for my front wheel and two more for each of my other family members' bikes. They're clearly visible from the side, and since no one rides a bike in a perfect straight line, they help ensure you're visible from both the front and rear. My wife usually frowns on frivolous things, but even she thinks it's pretty cool. I have had this item for over a year now and am still on my original batteries. I should probably get some spare batteries soon when they finally die.
