A relatively light weight, low cost compact safety light which may be worn or carried by athletes such as joggers, runners, cyclists, etc. is provided. The safety light is comprised of a light source coupleable to a battery power supply by a position sensitive switch which is sensitive to movement of the athlete and provides intermittent bursts of light which are highly visible to oncoming cars. In one embodiment, the light source is comprised of a light emitting diode coupled to one or more pen light batteries by a position sensitive switch such as a mercury switch. One or more lense members are provided to increase the visibility of the light generated by the light source. A first reflective means located within the safety light housing is utilized to reflect the light generated by the light source through the lense member while a second reflective means located on the outside of the housing provides additional reflectivity for the light generated by oncoming cars. The edges of the safety light housing are so angled or curved that the safety light can only rest on either its front or rear major surfaces, in which position the position sensitive switch is always off, thereby eliminating the need for any additional on/off switch. The light source may be operated from a battery source which provides current to the light source in excess of its maximum current rating to provide light of greater intensity than is normally producible from such light source. The position sensitive switch is so positioned within the housing that the light source goes on only intermittently when the safety light is being jiggled by the athlete in motion, and as a result the light source may be operated indefinitely in this over maximum rating condition without danger to the light source.
