I didn't know what to expect, given that they aren't that expensive, but they are amazing!! So versatile, extremely bright and visible from at least 100 yards out. They have so many purchase options, they recommend 6 per vehicle, bought them for every member of my family. One thing to keep in mind, they do not come with batteries and are not rechargeable. Other than that, worth the money.

I had 3 of these but got stolen I am replacing them because of this stuck to the hood of my car for over a hundred miles stop traffic when I was stuck alongside the road made him aware I was there and picked black night even a semi was grateful for our lights on a nice foggy date night during the day or great you can see them for miles these things are a lifesaver in so many ways thank you

I tried the lights at night, and they work very well. It got peoples' attention which caused them to slow down and pay attention to what was happening around them. I have put them in all my vehicles as well as showed my kids how to and when to user them. It was worth the cost. Recommend this product to anyone.

Work great when you have car troubles on the road at night. Very bright with a variety of flashing options. Also works while walking/running or riding your bike at night.

Stay safe out there.

They work very nicely
