Bests & Worsts Reviews from Amazon

This tape works very very well. I've used it on my bicycle, as well as on a headlamp I use for camping (the headlamp is black, so I put a strip of this on it so that it will show up when I search for it using my little LED button light). I looked at this tape here on Amazon, and to my surprise, I saw some negative reviews stating that the tape is not reflective. In some cases, this is true (but these are cases that aren't actually representative of the product's intended use). Here is why: the tape is retroreflective. In technical terms this means that when light is shone on it, the light is reflected back along the incident path, irrespective of the angle of incidence. Translation: when you shine light on this tape, the light bounces back directly towards the source of the light. So please, after reading this, don't shine your fancy high output flashlight from the level of your waist and curse the tape for being defective. When testing how reflective this tape is, make sure to use a headlamp (or place a flashlight next to your eyes) so that the source of the light is parallel to your line of sight. This will allow you to see what the driver of a car would see. Headlights on cars are placed right in front of the driver for a reason: so that retroreflective objects (traffic signs, bicycle reflectors, this scotchlite tape) will be highly visible to the driver. If this is your intended use of the tape, you ought to be thoroughly satisfied with its performance. I know I am.
