Review on Stay Safe And Stylish On Your Bike With DAWAY LED Wheel Lights - Waterproof And Fun Patterns Included! by Keith Desjarlais

This device was easy to install and produced the colored patterns as desired. I bought this for my 8 year old for a bike the night event our community held. He thought it was cool and so did others that saw it. As others have mentioned you do have to be moving a bit to see the full pattern display but the lights were bright and noticeable at any speed. If we rode more at night I would buy a second one so he could have them on both wheels and at the price I paid I may still do that.
