Are 986 Litronics plug-in-play?

[silver-S]

Both of my 2002's halogens are yellowed, pitted and have burned spots on the interior lenses. So, I'm looking to replace them and would prefer to install Litronics, if it's feasible.

But this comment casts some doubt on it:

Intensity doubles... and that seems to work for some.

Do the Litronic high beams work without the leveling modules or not? Sounds like they illuminate, so you get twice the output. Are the high beams not aimed higher. Does the rotation of the low beams give the long-distance illumination?

Thanks for any clarification.
