Light emitting diode (LED) signs made from blocks comprising LEDs that provide illuminated symbols such as letters, numbers, icons, shapes wherein the individual LEDs are not discernable as discrete dots. The signs may be used for commercial applications or any other application. A user may make a custom sign by ordering the symbols for the desired sign in the desired size and font. Each block comprises symbol(s) that may be constructed on a circuit board using LEDs. The block may comprise a background having a complementary color with respect to the LEDs. The blocks may comprise or couple with tracks or rails or other mechanisms such as wire that allow for low voltage power to illuminate the blocks symbols. An acrylic face may be mounted as the face of the circuit board to diffuse light so that the individual LEDs are not visible as individual dots, but rather as continuous lines.
