I wouldn't presume to understand the strange current routings of the 911, but I do know that new, same-maker bulbs all around (preferably Jahn or Phillips or other Euro-brand) have eliminated all the problems I once had in terms of signals, dash brake light, etc.

I spent that afternoon removing and cleaning signal/brake lenses, cleaning the signal buckets, pencil erasering contacts, and then putting in fresh bulbs with silicone grease and the result was a nice, even running light brilliance and no more signal etc. problems.

You might start by seeking the grounds for your signals and ensuring they are 100% clean. Total cost for the above exercise for me was about $6.00.
