Reflective jackets are a great safety aid for cyclists riding in the dark, if they have them and wear them consistently. A possible way to overcome a cyclists reluctance to wear the said jacket, say for example if they think to themselves, “I’ll be back before it gets dark or it’s too warm for my jacket” is to take the decision out of the equation.
Researchers have found that reflective tape attached to the rear frame of the bike and pedal cranks does the job of increasing visibility just as well as jackets do, but without any active behaviour required of the cyclist.
“Reflective tape is highly recommended to complement front and back lights in bicycle riding at night”, they conclude.
