Abstract: An illuminated, vibration-resistant wind sock utilizes a light fixture mounted for rotation with the wind sock and having a spotlight bulb directed along the horizontal axis of the wind sock to provide even, continuous illumination of the wind sock interior and to produce a dramatic glowing effect to observers of the wind sock. The bulb may be mounted directly to a rotating axle coaxially with the supporting post or can be carried by radial arms attached to the circular framework of the wind sock.
