Most of led safety flares are orange lights, I have been looking for red light for a long time until I purchased this set. I prefer red light because it can be seen more clear from great distance, especially in bad weather. Same quality as other slimk brand flares, By the way It is a little difficult to change the batteries, I used a small flat screwdriver and slowly applied pressure to one tab until the seal broke. It is must-have for your car emergency kit.
Haven't had to use them but they charged up with no problems and they are sitting in my car. I purchased a second set for my wife and they are charged up and sitting in her car.
