How to mod 9006 HID bulbs to fit in H4h opening in your JDMs

Octane · 12-06-04, 04:37 AM

I've had several people PM to ask how I did this, so I thought I would start a thread to explain - others who have completed this conversion please feel free to add your input!

This is what I recently wrote to an inquisitive member:

I bought a set of JDMs with the stock H4h bulbs still in them. I removed the H4h bulbs and compared the location of the filament on the H4h to the location of the gas pocket on one of my 9006 hid bulbs - good news is they are exactly the same distance away from their respective bases. This means that once installed the beam pattern will not be affected (btw JDMs have much more even light spread and beam cutoff than USDM headlights).

Now the only problem was to figure out how to carve the 9006 base to fit in the H4h opening of the JDMs. After looking at the opening, the stock H4h bulb and my 9006 hid base for some time, I realized that if rotated the hid bulb the right way, I could file off a certain amount of the tabs on the hid 9006 base to properly fit and hold in the JDM H4h opening. I can't get more specific than that without using pictures, but I'm sure that if you wanted to do this (and bought the JDMs and 9006 HIDs) you would be able to figure it out.

Once that is figured out, place a ziploc bag over the hid glass to make sure there will be no finger oils left on it (which would destroy the bulb!), then take a dremmel and carve the base until it has 3 prongs that will hold in the 3 prong openings of your JDMs.

If you have any questions feel free to ask!

Thanks for the help. I already have the JDM's now I have to find a set of 9006 HID's for a good price.

This may also work with D2S or D2R based HID bulbs, but I don't know for sure.

The big advantage with buying a 9006 kit is that the wiring is all plug and play in our USDM cars - you can just attach the car's stock 9006 plug into the HID kit (as the power switch), connect each ballast to the battery (as the power source) and insert the modified HID bulbs into the JDM kit. This removes the need to splice the H4h wiring to the car's harness.

Keep in mind that the higbeams are now yellow fogs, so you have no true highbeams - I find this to be no problem.... The hids are as bright as I will ever need and I can use the yellow fogs to flash people without blinding them. It also looks real nice with the yellow and HID light side-by-side..... just ask theGodfather!

Pic of beam pattern I posted in my G2 gallery post:

Now keep in mind this is with my crappy camera phone - in real life the beam is more even and the cut off is sharper. Also, it looks brighter on the left because I'm closer to that wall...

lol. I believe Dave was talking about finger oils from touching all over the bulbs.

dave, wouldnt changing the direction of the bulb make a differnce, i had some old 9006 bulbs at home, i messed around with them, and saw what u were saying. u can get the three prongs to cover up most of the JDM holes for the base, but wouldnt rotating the bulb affect the beam?

Nope.
Rotate the bulb and you'll see that the gas pocket is always in the same place!!

If the bulb was in too far, or not far enough, then you'd have problems with the beam pattern. But rotating the bulb won't make a difference b/c the light shoots evenly in all directions from the gas pocket. Ya follow??

Heheh - ya that was me! I took it out because there is a character limit and I used them all up explaining my mods!!

I even have more mods not listed in my sig because of the character limit, like my autodim gentex rearview mirror....

When I work a new sig pic (cole austin agreed to help me) I'll try to incorporate the mods in the sig photo compilation, which will free up characters to put that back in

Edit: btw I LOVE that sig pic of yours. So classy and mean looking all at the same time ...WOW. Every time I see that shot I drool....

Dave i asked the people on HID forum about rototing the bulb, here is what one person said "yes it would alter performance of the bulb and beam. Return wire needs to face straight down"
