ABSTRACT:
A road sign includes: a rotor disk rotatably mounted on a frame having a retroreflective sheet formed on a first surface of the rotor disk capable of reflecting any incident light projecting onto the retroreflective sheet for forming a bright surface of said disk, and a light-absorptive surface formed on a second surface of the rotor disk opposite to the first surface capable of absorbing incoming lights projecting onto the light-absorptive surface for forming a dark surface of the disk, whereby upon a blowing of wind on the rotor disk, the disk will be rotated to subsequently orient the first bright surface frontwardly and then orient the second dark surface frontwardly, thereby causing a flashing operation for serving as an effective road sign.
