Yetiman, that explains the difference between the two lenses, and what you say makes sense. However, it still leaves me with a non-approved lens. If what you say is correct, it may leave me with no option but to install the L691 & L692 light assemblies to get through inspection. Thanks for the additional info, it makes a little more sense, and expalins why I am having such a hard time finding DOT replacements for them (as they may not exist).
