Abstract: The present invention relates to light source for being supported on a visor device which is pivotally supported on a helmet between open and closed positions. The visor device supports the light source thereon for pivotal movement with the visor device. The visor device comprises a visor member and a mounting mechanism for pivotally supporting the device on a helmet with existing mounts. A power supply selectively powers the light source. The light source is mounted on the lower edge of the visor member such that the light shines forward when the visor device is opened to expose the facial opening of the helmet. Preferably, the light source is a strip of LED lights powered by a battery pack provided with a control mechanism for turning the lights on and off as well as adjusting their intensity. The light source may be pivotal relative to the visor member.
