i got the ebay h4 conversion set up on my 99xj sport,and then put in a 10000k hid kit ,it took about an hour to do all of it was plug and play.the lights were about 35 w/shipping and 90 for the hid kit.
word to the wise i got the blacked out projector style at first they were horrible even with the hid kit couldent see ****.

 

im also curious about using the Ultra Blue 100/90W, would i have to upgrade any wiring?

 

http://www.vvme.com/12v-5055w-h7-hid...-kit-p-87.html, i have installed this 55W VVME HID Bulb for 3 months, everythining is OK.

 

I got the H4 wiring upgrate kit that is plug and play with the relays, and hooks to the battery, and along with that some H4 housing off ebay for like 30 bucks. Pep Boys for some brighter white bulbs and can see ton's better. With that H$ wiring upgrade, I can go to a 100w bulb, just ordered some, but haven't put them in yet.

And BTW, I'm up in MN and gets pretty darn cold u here in the winter as well, and haven't had an issue with the bulbs last winter. Haven't run them with the new better wiring tho, but can't see how that would effect negativily.

 

This is what i did....loving it, day and night.
Easy 30 mins job.

H4 / 9003 Head Lamp Heavy Wattage Wiring System Kit
IPF Rectangular Headlight Housing
H4 100/80w Hella Standard Bulb (you might want to stay with 60/55w to stay legal)

GL.

 

I wouldn't run 100W bulbs on stock wiring, there are lots of guys with burnt headlight switches even with stock bulbs. Seems like a recipe for underdash fire to me. And the voltage drop wouldn't give you the full advantage of the new bulbs. Better to run relays, and heavier wire from battery. (Kits available, use existing wiring to pull in relays, that switch power from battery through fuses then directly to headlights)

 

WHY just bright light??

 

thanks all of you .
