I really like the way JDM headlights look on a kouki and I finally had some cash to blow so finally got a pair. When UPS dropped them off today I ripped open the box and my first thought was "sweet, I cant wait to put them on". How hard can it be they should fit right in no problem, right? Wrong, my next thought upon further inspection was "WTF" when I noticed that the JDM high-beam doesnt use an H3 bulb like the USDM. It uses an H1, the same bulb the low-beam uses. Hmmm.......here check it out... the top one is the JDM......


I dont know why they did it I just know they did. Its those subtle defferences like that that get you everytime you go to put a factory JDM part on your USDM car. It doesnt happen all the time, just sometimes.

The wiring harness for the Jap headlight which has 2 H1s uses a 4 prong connector(2 wires per bulb).

The US headlight only has a 2 prong connector(1 H1), the H3 bulb uses a seperate connector that plugs in directly to the bulb.

Well thats nice...to bad I dont have the male end of the 4 prong connector.
But that would be too easy wouldnt it?
Heres what I did.
I used the low-beam(H1) connector from the US headlight and put it on the JDM low-beam.


Then I took the JDM harness and cut one of the H1 connections off at the plug.

Then I went looking for some type of 2 prong connector, preferably one that was weather prove. Hording is a disease that runs in my family so finding a couple sets of 2 prong sealing connectors was as easy as walking out in the back yard and scavaging off an 84 celica for them.

Then I connected one end of the plug, in this case the female end, to the H1 connector I got off the JDM harness.

Now theres the matter of the H3 connector on the car.

Its as simple as putting the other end of the connector in its place. Oh yeah I should'nt have to say this but I will anyway...try not to get any wires crossed up.

Then just repeat the process for the otherside, install the headights and stand back to enjoy the fruits of your labor.

Some of the first things that came to my mind when I was done were....."Was this s*#t really worth the time and money?"and " Now I gotta sell the old headlights the get back some of the money I blew"and "I should be saving for a motorcycle, gas aint getting cheaper".

Anyway I hope this will be helpful to somebody.

on the right up

I have to agree. No offense, but it makes the kouki look like it has down syndrome.

there just not that different.

looks as good as the usdm ones...

japanese lights are 100000 times better than the us lights.

Yes, Brian we all know JDM headlights are 1000000000 times better...

anyway does anyone know if jdm zenki lights are bolt on too or would i have similar prob. w/ the high beams?

Ummm........you guys do know that the headlights can be adjusted both vertically and HORIZONTALLY, right? They come from Japan preadjusted to the left. All you have to do is adjust them to the right.

But the rest is opinion so "To each his own".

are you serious? i guess you dont know anything about lighting then.

LHD beam pattern goes like this

_____/-------

it flares to the right.

RHD beam pattern is this
-------\_____

it flares to the left

its not a matter of just adjusting it down.

learn your **** before you start spreading misinformation

anyway, can you get any NIGHT shots so we can see how different it looks at nighttime?

Well.....I stand corrected.
So now I'm curious....Its the lens of the headlight that dictates the pattern right? You can adjust the beam but not the pattern.

a projector is consisted of the lens, reflector bowl, and the shield. the shield is what determines which way it flares up

You know you can change the shields as well...or even make your own, its not hard. Yeaaaaahhhh.............................
