Michael Mandiberg developed a kit for making your bike super visible to car headlights with retroreflective vinyl tape! It’s easy to apply, looks fly, and comes in several colors. I did up my ride too, check it out above in normal light and below in flash (simulating headlights). The kit makes a great gift for your cycling friends and family members.

    Those look really nice, I love the wheel pinstripes. I bought a chunk of SOLAS coast guard-style reflective tape for my bike and helmet (like this: ) and some reflective cloth strips to sew on my bag.
