The sign is made from coloured ABS plastic and includes two LED lights which are white, red, blue or yellow in colour which are solar powered via a battery. A single digit, optionally in combination with a letter, is illuminated by the LED lights. A light dependent resistor is used to turn the LED devices on when the light is poor. |
