Quick AI lights question

I've been reading through this forum, and Paul's guide of course, as I try to make a decision whether or not I want to wade in to DX10 waters. 

One thing I'm not clear on, is how DX10 with the Fixer impacts AI light visibility.

Are there any workarounds for the user aircraft landing lights having to be on, or is this just a tradeoff that must be made ?

I do not use addon scenery, other than ADE edited defaults, and I am not so concerned with how the user aircraft external model looks, but AI traffic is something I have invested far too many hours in to compromise much on lighting/appearance. I totally understand if it's not fixable, but would rather get feedback on that now before going any further.

Thanks in advance.
