Good to know - I ride a recumbent trike (low to the ground) on some ... not so bike friendly DFW, Texas roads (even with signs and near a school) and the brighter & Redder the better.
I guess the right side...
Great guesses everyone! It is really interesting comparing the two, especially on camera. A pyrotechnic flare has a white spot to the center of the flame which actually puts out a good amount of white light rather than red. In the picture, the real Flare is on the right and you can see the white in the center as a burst which gives it away. Our FlarePro on the left is actually much more "red" in color and red intensity than a real red flare. This was interesting discovery for us to realize! Our FlarePro is the most intense red light you will ever have seen and from a few meters away it is indistinguishable from a pyrotechnic flare from all angles. :)
