Edge-lit LED signs are an attractive and innovative way of advertising your businesses and products. They are energy efficient and are easy to assemble from acrylic panels and LED tape or strips. The key to a good sign is how you laser the image or lettering on the acrylic sheet and how you mount the acrylic panel so that the edges are brightly lit with the LED's . Colored LED's or multicolored LED strips and tapes enable you to choose the color of the light in the sign. The engraved parts will light up while the rest of the sign stays dark, producing the illusion of floating letters or images.
