Would be, but also misleading. As I mentioned before, its not possible
to know which plugin is loaded. So to be more precise, the condition
would have to be something like:

[hasRecordOnPage = tt_content : list_type='indexed_search']
page.includeJS.lightbox = fileadmin/res/lightbox.js
[global]

So specifically doing some kind of "query" for certain records on the
current page (in this case a "tt_content" matching
list_type='indexed_search').

Cheers,
