I'll see what i can do and get some pic's.

Even though my lude is a uk spec it has got the black backed one piece lights which i was told were JDM spec, they must have been put in after its front end smash by previous owner.

all the info i've got to hand is that they are 6000k, the code for them is H4VDXKIT, the only thing that i had to do is disconnect the little box of tricks that puts a low power through them when side lights are on, so the halogen bulb on the HID is not used, but i'm going to have a go at wiring this into the full beam wiring so i'll have even more light when every thing is switched on

These kits are available from Larkspeed.

The JDM lenses are plastic, so you'll be able to tell if they are by tapping them, the UKDM's are glass.

It has a halogen bulb on the HID?

Interesting point Dave, i wonder if if even comes into it or not?

pic's arnt very good, only got a camera phone!

as you can see it has a 2nd halogen bulb and a reflector like the H4's, i no the H4 has a double filament but the lude only uses 1 of the filaments which i've always wondered why, why not just have a single filament bulb?

Hmm, that's quite interesting, someone may correct me here, but as i understand it, that large shield on the bulb isn't standard and may be why you get a good beam from it.

Thanks for the pictures, they're perfect for the purpose now are you willing/able to post up beam pics and maybe even a comparison between the HID's and the H4's fitted instead?

Thinking about it, that bolt on halogen bulb isn't standard either.... wonder how you go about replacements?

I'll try and post beam pic's when it gets a bit darker

I'm not to worried about the halagon bulb as it's not used (yet)

you say the sheild is not standard, do you mean on the HID's or on the standard H4's?

No, i mean on the HID bulbs generally, i'd have to check, but i'm really not sure they're like it shows in the picture here.

Hmm, just did a quick search, it seems that the H4 bulbs do have a kind of extended shield on them, but it varies massively between bulb makes....

Again, this could go some way to explaining massively varying results from people testing HID retrofits.

Another search came up with these which i found *very* interesting and would appear to be very useful for anyone with HID bulbs retrofitted.

Also check another picture of them with a bulb inside;

Well i'm glad i went for these, instead of e-bay special's they really do make a difference. there not the cheapest but i was told by a mate in the trade they are fairly good ones. I'd bought them ages ago but due to the low power that was sent to the bulbs when on side lights they started flashing. But thanks to someone at the last north wales meet ( sorry can't remember their name) who told me how to disconnect it, they now work ok

Yeah, that's just the sidelight resistor in the front bumper, unplug it for that.

Well, as i said, the pics i found of the H4 HID bulbs seem to show varying designs/types of shield, the best beam patterns i've seen come from the full shields, as shown in that link above.


Can't see any UK distributors right now but i do see a lot of forums making their own.

Of further note, i also see someone who found more help shielding the underside to clear up some flare from the top of the beam. No further info on that though

H4 HID:

H4 is constructed to use the upper portion of the reflector only when low beam filament is on. An internal shield in the H4 bulb will reflect light going downwords towards the upper portion. When you turn high beams on, low beam filament will turn off and high beam filament lights up. It is mounted a little away from the low beam filament, so the beam will hit the road further ahead.
So what happens if you slam an HID bulb in there, correctly mounted in the focal point? Very simply, the entire reflector will be used and even the orange light that normally emits from the lower portion of the HID bulb will be visible on the road. In other words total useless light. By having the HID return wire of the bulb turned down and using an appropiate shield made in stainless steel or aluminum should correct most of it. Both Phoenix MicroLite (Bob) and suvlights.com (Jen L) have premade H4 adapors/shields. Also be aware of possible stray light issues (See above). From time to time Caspers Electronics Inc. (located in Illinois, USA) stock some good quality H4 adapters for D2S bulbs. If you do not see them listed on the site (P/N 103016), inquire per phone. They will not be a plug and play, but it is an excellent basis to make a quality H4 HID retro.
Many kits out there makes you give up high beam. Some people claim that HID will give you the extra light, so high beam becomes unneccsary. This is not true. There are high/low kits you can use - see "aftermarked Bi-Xenon kits" on this page.

Physical measurements:
base to start of filament: 28.5mm
glass diameter: 17mm
base to tip of glass: 59mm

My HIDs have the shield inbuilt into them, rather likie the ones pictured.
