15. One or more of the color vision screening tests currently approved for use in the
aviation industry (for example, the Farnsworth Lantern screening test) are not
adequate; these tests should be identified and their use discontinued.
The way I read that is the test in the parenthetical is merely an example of an approved test, not an inadequate one. The last clause supports this. The inaduquate tests need to be indentified. Farnsworth Lantern is still good to go. Farnsworth flashlight (whatever that is) is not ok as per the AME guidelines.
