As for Capacitors.....well, there are many that will argue both directions, but in my experience as an installer for 25+ years, they are a waste of money Unless you have a sufficient charging system behind it. They add additional strain to your charging system because they are constantly being depleted and need to recharge. Spend the money upgrading your charging system if you feel the need for it.
Just a side note, and someone correct me here if I'm wrong, but the newer cars with HID headlights will not dim like older models because they are ballast controlled.
Just my 2 cents......
