Not going to be much help here, but thought I would share my experience.
I was inspired by the thread on LED rear lighting to improve the same on my haze. One of the improvements was to add cateye LEDs to the sadllebags. The cateyes have the cabability to be wired as brake/running/signal, with the signal being separate of the running/brake.
Cool lights, very bright...but I ran into the same problem. The haze could not handle the signal portion. The tech shop I use, suggested a load equalizer for each light. I decided to use the cateyes for brake/running and not fight the turn signal issue. They are doing an excellent job and the haze finally has bright and very visible tail lights. By the way, we did wire the amber rear turns to function as running/turn, again increasing rear visibility.
Sorry, I don't have a solution [smiley=nixweiss.gif], just thought I would share the experience.
