With a username like that, should I say Semper Fo?
The new Jeeps have headlight and accessory running on partial direct current. They take a section of current and divide it up with computer code to alternate between accessories to get that small fraction of fuel efficiency out of it. I feel your pain, our older XJs had headlights that really sucked too. I am not sure what would happen if you wired them direct to the battery with a relay. But your D3S bulbs are popular and there are some brighter ones out there. From what I could find out, you want the 35 watt bulbs
