Review on 🔦 Enhance Safety with LED Safety Lights + Bonus Features: Clip-on Flashing Strobe Light for Running, Jogging, Walking, Cycling, Reflective Gear for Kids & Dogs, Bicycle Helmet Accessory, Bike Tail Light by Marcus Merritt

I bought a set of 3 red turn signals. My first thought upon opening the box was how tiny they looked. I checked the Revain again to see if the sizes are shown and they are, but you won't get a sense of the size until you actually see it. All three fit in the palm of your hand. However, they will do their job. Especially in one of the flash modes. I turned them on at home during the day and have no problems with the brightness. Perhaps those who said the light is weak have an old battery. Again, for the sake of brilliance, the purpose of these flashers is not to be seen with them, but to BE SEEN by others. The back closure is very strong. I have another brand with an elastic strap and you had to use that because the spring clip on the back was so flimsy it wouldn't attach to anything. There are no problems with this. As advertised, they come with 2 spare CR2023 lithium batteries. You can find standard batteries everywhere. They also come with a small Phillips screwdriver. Don't lose it if you don't have a screwdriver to adjust your glasses. Velcro straps are 10 inches long but will stretch to about 14 1/4 inches. Of course you'll need a few inches of overlap to hold together.
