Review on Strobe Warning Outdoor Traffic Highway by Tom Motko

Great idea, decent build quality for the price BUT CHEAP, THERE WERE FAST LEDs. INVISIBLE DAY and barely visible in total darkness. You cannot change the blinking pattern, so the device cycles through 4-5 different patterns with a significant delay (nothing is lit) between the last pattern and the first. It is a pity that this manufacturer does not rely on brighter and higher quality LEDs. The slight additional cost of using a better quality brighter diode and the ability to change the flash pattern into a set would make this flashlight a superb product. Very very disappointed. Hope this helps you with your decision. Good luck with your search.
