I dont think the fish give a crap about the sound korkers make or a light or any other stuff you can think of,,, initially they may be spooked but it wont last,,,,,
If it did then the fish would never be behind you when you wetsuit out with your light on then claw your way up on the rock,,,, let alone chase a plug 3 feet from someone in the water while swimming,,,, fish are curious by nature.....
ok,, now let it fly,,,
