Pinstriping with retro-reflective tape, a hobby of mine ; looks great all day, protects you at night! I do my helmets also! 3M reflective tape , get it on Amazon. The light source is a 150 lumen pocket flashlight from 20 meters(18 yards) away.
It increases the visibility truly. I can not expect how the material will develop by time, due to weather conditions and chemicals which occur on our tours.
