Review on Bike Light Set - Front and Rear Silicone LED Bicycle Lights (6PCS) - Waterproof & Safety Road, Mountain Bike Lights - Includes 10 Extra Batteries by Bryan Fields

Fairly cheaply built (the only reason I don't give it 5 stars) but excellent for its intended purpose: attracting attention. Of course, do not confuse these lights with real navigation lights. But they will take you home in a pinch and will "see" you for sure. I'm not sure if any of those previous reviewers noticed, but these lights come with a small plastic electrical insulation strip that needs to be pulled out before use, and if you don't you'll think you're empty have batteries.
