the rheostat ring with optical fiber allows you to adjust the brightness of the pin
the ring can also be used without the pin but with a perforated lens and fiber, to eliminate the distraction of the pin
rotating the rheostat so as to expose the fiber more to the light will increase the brightness of the pin, covering it more will decrease it!
the ring is prepared as standard with the green fiber mounted, but also includes a red and a blue fiber.
