A light that is mounted on a clamp. The clamp is configured to be attached to different locations on a user's body, and is sufficiently sturdy so that it can support the light in an illumination direction that is fixed relative to the user's body. The light is connected by a cord to a power supply, such as a battery pack or an AC adapter. If a battery pack is used, the battery pack may also include a mechanism, such as a clip, for attaching the battery pack to the clothing or belt of a user. A headband is provided to which the clamp may be attached. The light is pivotally attached to the clamp so the light may be pivoted to illuminate in a desired direction. In addition, the light is rotatably mounted on the clamp arm, permitting the light to illuminate in a wide variety of different angles.
