Abstract: An illuminated safety or security barrier is shown for preventing children and pets from gaining unauthorized access through passageways. The barrier may optionally be a gate allowing authorized passage. The barrier includes an electrically operated light disposed to illuminate the barrier directly, to project a visible signal away from the barrier, or both. The barrier includes an electrical system having a battery or plug and cord to supply power, controls, and conductors connecting the light, power source, and controls. Optionally, the controls include a programmable timer or a photocell or a motion sensor to inhibit operation of the light, and a manual switch which controls intensity of the light. The various controls may be combined if desired. Optionally, a remote controller is provided.
