Teardown of LG-1 light ring for Olympus Tough cameras

The LG-1 light ring picks up light from the LED, and guides it into a ring around the lens.  It uses the camera's LED light.  The LG-1 is a purely passive light guide, and it doesn't carry it's own light source.

I question the function of the "pan handle" to left of the intake window for the LED light.  It's in a way of the flash.  The manual for the TG-5 says that the flash must be turned off when the LG-1 is attached.  It's painted white probably to reduce heating if the flash fires accidentally.  I might end up hacking off that [seemingly] unnecessary bit.
