EASTWILD USB Rechargeable Bicycle Lights Set Front and Rear, Bike LED Light 2000mA / 900 Lumens Super Bright Bike Headlight, Free Rechargeable Tail Light and Helmet Mount Included (Black)

Like it

make sure you know where to plug in the back light to the cable, hard to find the opening, but works really well as a helmet light

mounted this on my helmet for winter night time riding. Recharges by usb so I just bring it into the office and recharge there.

Just as promised

Works greatSeller responded quickly to defective produce with a new light

I had high hopes by reading the reviews, this is no where near 900 lumens. I hate that Amazon let’s people lie about their products! The battery does last a long time, I timed it about 3.5 hours on high, but that’s because it’s not 900 lumens. There’s also no way to contact the seller either. The pictures are the light on high, then the light on high next to my 350 lumen flashlight. Not happy and I’ll probably end up returning it.

The red rear light does not work. Otherwise bright. I didn't test battery life.

The back light or rear light does not work at all after a few hours of using it. I wish they could replace it..the front light is ok for now.
