I see in this post where several people have tried only bulb replacements to improve the headlights. Some posts were older on this so has anyone found a successful replacement bulb that provides better lighting without having to go to the complete HID kit. If so, list details of what bulb is used.

 

Halogen bulbs will prob never make you happy. Just put in an HID kit and you won't be disappointed. I got mine here...
