I would recommend the CE headlight harness and upgraded bulbs. I run the Sylvania Silverstars with the CE harness and very pleased with the results. The harness has a diode inline that allows you to run both high/low beams when the highs are on. With the harness the headlights are powered directly off the alternator or battery junction block. The claim is 30% brighter. Coupled with a good bulb it's as close to HID as you can probably get. My 2 cents ...
Super HeavyDuty Headlight Brightener (booster) Harness.
Creates a direct power circuit from the bat/alt and provides a four light high beam capability.
