FAA Rejects Farnsworth Lantern Test

"Important note: The FAA no longer accepts The Farnsworth Lantern D15."

I just happened to stumble on this. I have been planning to take the
Farnsworth Lanterns test. Seems it's no longer accepted by the FAA. For
AOPA members, here's the link:
http://www.aopa.org/members/files/medical/colorvis.html

Also according to that link, you can only take the signal light test
twice. After that, they may refuse to allow you to take it again.

The link also lists the following as acceptable substitutes. They
recommend trying to pass one of these with your optimologist before you
apply for the signal light test. Anyone have any idea which one is
preferred since the Farnsworth test is no longer allowed?
* Keystone Orthoscope.
* Keystone Telebinocular.
* LKC Technologies, Inc., APT-5 Color Vision Tester.
* OPTEC 2000 Vision Tester (Model Nos. 2000PM, 2000PAME, and 2000PI).
* Titmus Vision Tester.
* Titmus 11 Vision Tester (Model Nos. Tll and TIIS).
* Titmus 2 Vision Tester Model Nos. T2A and T2S).
