Rail Reflective Tape
Using rail reflective tape is very simple and useful in many different ways. Rail Reflective tape works by redirecting sunlight, or any light source back to its originator. For instance, if two individuals were walking down a street, one has light and the other has the reflective tape.
If the person that has the light shines it on a surface that is covered by the tape, then the tape will send the light source back to them. The other individual may not see the tape through the light. The reason for this is because the rail tape can either be covered by glass beads in the material, or can be created with rectangular prisms that collect and trap light, and then direct back to where it came from.
Look at it this way, if you were in a round area and you happen to be the center of the space, and you throw a ball towards a wall, more than likely the ball will be sent back to you. In a sense that is how reflective tape operates. Another fact to consider is that unlike regular tape, rail reflective tape does not have to be in a horizontal position to the person holding the tape for the light to be seen. It can also illuminate several beams going in separate directions all at one time. If you want the rail tape to work at its highest, putting up against a flat surface will work just fine.
Remember that reflecting can only be achieved if your eyes are in the direction of where the light is traveling. Let's say for example, you step towards a stop light and the rail reflective tape does not reflect any longer. The reason is because the angle from which light has crossed to reach your line of vision has become too intense. The direction of where light travels in correlation to your sight will play a pivotal role on how reflection will work.
Using reflective tape can be useful, and can help you see in places that you normally would not be able to. Depending on what it is needed for, you can use rail reflective tape that has the glass beads, or the prisms. Whichever works best will be effective.
