Pelican 2130 LED Mini Flasher, Red

Not a flashlight in the normal sense of the word, the Mini Flasher is a flashing safety light that keeps track of joggers, hikers, children, pets and can identify equipment and campsites at night. Submersible to 500 feet, the Mini Flasher is ideal for anyone to use as a warning or emergency light.
This small 1 oz light includes a heavy-duty clip and ring, which can attach to anything, making the Mini Flasher easy to pack or carry when not in use.
