A lighted sight pin for archery bows which provides a small point of light for aiming the bow in dim light or at night. The sight pin is structurally protected against damage by brush, tree limbs, etc. and is completely solid state for dependability and long life. A fiber-optic rod transmits light from a light-emitting diode (LED) activated by a voltage source to the sighting end. The light-transmitting rod is surrounded by a rigid shaft or tube. The LED is spaced from the sight end of the rod, allowing the sight end to be extremely small for accurate aiming yet easily visible and fully protected from damage by the rigid shaft or tube and other structure.
