Turn Signal Flasher Unit problems of the 1997 Jeep Wrangler

Sirs, I have some general concerns, and could not find another area on the web site to address them: I can not understand why the same lights that mark brake use, also mark turning. When someone is tapping brakes and has turn signals on, it is unclear what their intention is. I also do not understand why we have running lights on all the time. I have to dim my rear view mirror to avoid being distracted by these lights, which defeats the purpose of these lights.
