BRIGHTEST REFLECTIVE - 330+ cd/lx/m2 at 0.2/-4 degree angles. That meets the reflectivity brightness standards for highway brightness. 10 times brighter than colored reflective (like black or yellow) because it uses tiny mirrors. This will make you visible to drivers by reflecting the car's light back to the drivers eye.
ANY HARD SURFACE - Put these decals on your helmet, bicycle frame, bike rims (not for rim brakes), car, motorcycle or stroller and it will make you stand out to drivers to keep you safe. Just peel and stick with firm pressure.
PEDAL AXLE - Specially designed rectangles that fit most SPD/clipless type pedals (which typically don't have reflectors).
KIDS SAFETY - Add a decal to you children's bike, scooter, roller blades or any smooth, hard surface. It will stick to some shoe uppers.
