^^^ yep. The only real way to get marked improvement from the headlights is to retrofit a projector and run either an HID or LED bulb.
I did see a post in another forum where someone ran some German bulbs that drew more power, so he ran a relay and some heavier duty wiring. The output was definitely improved but you almost end up spending the same amount of money to do a projector retrofit (yourself).
