HID Replacement Kits on Ebay
 

Does anyone have experience with the h4 replacement kits on ebay? arksen-motor and zpeedstarz kits are around $65 bucks and the vision-technology package is $80. I wanted order Friday but will put something in Monday. They all have 30-60 warranties but there are some vendors for the HID h4 kits that offer 1-2 year warranties if you buy the separately.

I was a little worried that buying the bulb shells separately might be problematic for fitment. It does look like there's plenty of room behind the headlamp though for the 4-5" that the bulbs protrude back.

If anyone's replaced the sealed bulbs and has thoughts on this would love to hear your experiences.

I'll approve this separately.
You can get Hella Projection cases to house the Halogen bulbs James.You can put in what ever wattage you want,But after say 50 watts it is best to add a relay.The power goes through the Switch so it would burn it out.
The cheapie Ebay housings are about 35 bucks.
Hella is Glass,and is built better.
If you are just looking to Spend Minimum Bucks,then the Best Bang for the buck would be Sylvania Superstar Ultra Headlight replacement unit.
Full sealed beam 6054 .One set is about 60 bucks.
