Abstract
Disclosed is a light pipe signaling device for signaling a user. A light pipe has a first end portion that fits into a receptacle. Both light pipe and receptacle are constructed using a transparent material. Light from a light source enters the receptacle and is transmitted to the light pipe. The light travels along a body of the light pipe to a second end portion. The second end portion is adapted to reflect or dissipate the light such that the user is able to see the light from a wide field of view. The light pipe is preferably removable and the receptacle is preferably incorporated into a device that activates the light source in order to alert the user.
