These reflective straight strips are great on anything that needs to be seen at night. Perfect on cars, motorcyles, bicycles, helmets, strollers. Create your own custom design with these strips. You can cut these down to shorter pieces or overlap them to make longer strips. The unique triangular pattern on the material camouflages the overlaps very well, so that it makes the overlaps seem seamless. They reflect light back at the light source that shines on them (like incoming headlights), giving the glowing effect. Unique triangle patterns, with high "glass" gloss. ALL reflective materials will tend to look more intense in pictures. Camera flashes can be more intense in a split second than other lights. LEGAL in most places since they are made for SAFETY on vehicles, and are NOT lights!! These are NOT "glow in the dark." ***THESE STRIPS SHOULD NOT BE USED ON THE RIMS OF WHEELS. RIM TAPE ARE CURVED STRIPS AND ARE SOLD SEPARATELY.***
