An illuminated bumper assembly having an elongated light source for emitting light rays and an elongated bumper for carrying the elongated light source. The elongated bumper is adapted to allow light rays from the elongated light source to be emitted along its length. In some embodiments, the elongated bumper has a primary bumper surface that faces away from a protected surface, and the elongated bumper is structured to engage one or more approaching objects and at least partially protect the protected surface from the one or more approaching objects. In some cases, the elongated light source may be situated between the primary bumper surface and the protected surface such that the primary bumper surface also helps protect the elongated light source from the one or more objects. The illuminated bumper may be adapted for use on boats and/or other applications, as desired.
