this is at least 90% of the information you need to install '96+ JDM headlights (JDM model years, 1 and 2 piece) into the '99-'03 USDM galant. don't blame me if you try this and you are not qualified to do it. print this out and hand it to your tech at the bodyshop if you are scared or don't think you can pull it off. it is not terribly dificult to install JDM heads but you are cutting metal and modifiying your car. these are not simply bolt on.

that being said, here goes (copied from one of my old posts):

you will need to cut the metal near the inside edges where the headlights fit into the subframe. also you will need to bend the radiator rails for clearance as well. the 2 mounting points for the headlights remain the same (top and corner) but you will have to make a custom brackets or use a longer bolt into the radiator and drill a hole in the mounting tab of the headlight housing for the inner mounting points behind the upper grill. also if you get a JDM grill you will see where you have to trim some of the plastic on the back to make the grill clip in fush as well as make a small hole for one of the mounting clips. once you get your JDM headlights, compare them to the us spec and remove one us spec to see where you will have to trim the metal and some plastic on the housings to fit. the wiring is another story but it's not too hard... you will need to buy a pair each of H7 (low beam) and H1 (high beam). the corners thankfully just need a little trimming to the bulb socket (not the headlight housing) to fit and are wired and work just like stock.

my lights have a custom relay network direct from the battery triggerred by the stock wiring... i did this for my dual HID's but since HID's draw less power than regular bulbs, this was totally uneccessary and the stock wiring should hold up to any regular bulbs you put in.

now your going to do the following for each side of the car: basically to convert the H4 bulb (3 wires) to dual bulb (JDM H7 lo, H1 hi - 2 wires each, 4 total) you just need to do some wire tapping... you can even keep the H4 wiring and plug intact. basically, you tap and add wiring to each of the three stock wires ahead of the H4 plug. there are 2 positives (one for hi beam and 1 for low beam) and 1 ground (-). now just add another tap and wire to the ground (your going to need 2 of those total). the H7 low is easy, just add a female spade connector to the low beam positive and also another to one of the grounds (-); those then clip onto the bulb (H7 has 2 terminals and 1 is poitive and the other negative... they are interchangeable). the H1 is almost as easy... add a female spade connector to the hi beam positive. the other ground you extended will screw under the screw on the headliight housing itself that holds the clip that holds the H1 bulb. the reason this has to go directly to the housing is that the H1 bulb only has 1 terminal (+), the ground is the bulb's mounting collar and that contacts the headlight housing and clip. so now the clip that holds the bulb is the ground and then just clip the female spade connector onto the H1 terminal and it will have access to power.

btw, the corner 1157 sockets will fit into the housing w/ minor trimming. the grey plastic socket has locking tabs... 3 narrow and 1 wide. trim the side of the wide one down so it matches the other 3 and it should just push in and turn like US spec. also w/ this method there is no need for a new bulb / socket / wiring; it'll work just like stock

now for the diode trick...

there r 2 positive wires that go to your H7 an H1 bulbs... u want to bridge those wires w/ a diode. a diode basically is like a one-way-valve for current. you want to have the high beams (+) send power to the low beams (+), but not vice versa so that when you hit your brights, your lows stay on drawing power from the highs; not the other way around.

http://www.the12volt.com/images/12voltdiodes.gif

http://www.the12volt.com/diodes/diodes.asp ('http://www.the12volt.com/diodes/diodes.asp')

you want the ANODE side (no stripe) connected to the high beam positive (H1) and the CATHODE side (w/ stripe) connected to the low beam positivem H7). i soldered the diode to a short length of insulated wire at each end to lengthen it then wrapped the diode in electrical tape. you can simply splice these wire leads into the harness on the wires that lead to the bulbs.

the diodes you want are rated for 12VDC. you can get them at any electronics store like radio shack.

edit: it's come to my attention that in some cases the diodes have been burning up from upgraded bulbs (i'm running dual HID through relays so my diodes never see high amps). the solution for this is to just replace the diodes w/ SPDT relays to draw power directly from the battery to power the low beams when the hi beams are activated.

http://www.the12volt.com/images/relaytextA.gif
http://www.the12volt.com/relays/relays.asp ('http://www.the12volt.com/relays/relays.asp')

as in the diode trick instructions above, just replace the diode w/ a SPDT relay (like used for my bright corner re-wire).

85 taps into the high beam positive (trigger)
86 taps to a ground
87 taps into the low beam positive (output)
30 taps directly to the battery (you may want to put a fuse on this line)
87a not used (must be insulated as to avoid a short)

good luck!

edit: OK, by popular demand, here's pics and added info from:

jdm Headlights - Problem making them flush (pics) [Resolved] ('https://www.thegalantcenter.org/viewtopic.php?t=42419')


mine site pretty flush, but i cut EVERYTHING to get them that way. you will have to cut more out of the inner mounting tabs on the headlights themselves then drill a hole in them and use a longer bolt to go into the radiator/ ac condenser mounting holes. i took crappy pics w/ my phone last time i had my grill off... lemme find them.

OK found them and made them as big as possible since the quality is ass.

so how are the jdm headlights supposed to light up? standered headlights for one bulb, and dual bulbs for high beams?

outside pair are low beam, inside pair are hi beam; when high beam is activated, both low and hi should be on (four beams at once).

I did this for someone a while back, and now I'd like to add it here. This should help out those who are looking for pics before starting to cut.

I started out cutting the metal by the radiator. Have a basic line to follow (I used a silver marker), than just trim more as needed. Just don't forget to paint them when you are done with everything. I used a dremel, just get enough cutoff wheels ready lol.

On the pass. side head, you'll have to trim the bulb housing, because it pushes against the ac line

http://i54.photobucket.com/albums/g93/OneBlackGTZ/jdm%20heads/100_7310.jpg

Here's how I trimmed the inner clips on the heads. I cut a lot, but I'd suggest to go slow, cut and try, cut and try first, so you dont cut too much, you might get away with less cutting leaving the thing stronger

http://i54.photobucket.com/albums/g93/OneBlackGTZ/jdm%20heads/100_7378.jpg

I used a spacer cut from some gardening-hose-fittings so the heads don't push against that square metal bracket. I also trimmed/cut the side of the radiator, but don't do that just yet, you might get away with just pushing the whole thing back.

http://i54.photobucket.com/albums/g93/OneBlackGTZ/jdm%20heads/100_7388.jpg

Some shots how things line up. Note on the upper right corner: you have to push back the radiator too, by relocating the bracket to the second hole. After all these done, you still might have to trim from the back of the heads, keep trying and you'll see where it hits something.

http://i54.photobucket.com/albums/g93/OneBlackGTZ/jdm%20heads/100_7527.jpg

You can also see how I cut the upper clips on the grill, flipped them and bolted them to the right place, so it clips into the original holes. On the bottom it still clips into the jdm heads. You also have to trim the top of the grill a little bit so it doesnt stick out, you'll see where.

Here you see why I trimmed the head the way I trimmed. I used a longer bolt with some big washer to hold in the headlight through the upper clip that's originally for the grill. This way it bolts into the original hole on the frame.

http://i54.photobucket.com/albums/g93/OneBlackGTZ/jdm%20heads/100_7652.jpg

Right lower corner: I trimmed some from the bumpercover, so the heads can sit lower, you might not have to. And if you have a JDM bumper you should be set.

I know this is a very old thread, but I have to ask if you have done anything to the reflectors in the lamps. JDM lamps are oriented to the opposite side to the standard lamps in USDM and European Galants, since the Japanese drive on the left side of the road.

Or, are you buying JDM-style lamps with the reflectors already changed to work on left-hand-drive cars?

Sorry if my question is unclear, I'm not very much into the technical terms when it comes to cars (yet). :)

spdracr
09-21-2008, 05:17 PM
the reflectors remain untouched as far as i know, if u can get urself a set from the Philippines or another country that has the JDM galants with the left hand driver then you might get lucky other than that then you will have them the way the japanese have them

actually, on LHD cars, like ours, the lights angle to the right to help the driver see better. on RHD cars, like JDM cars, they angle to the left. So JDM spec headlights in LHD cars, the lights point at incoming traffic.

it matters what side of the car you are on, because that also indicates (mostly) what side of the road you are on...

RHD and LHD beam patterns are opposite of each other. the "kickup" on the pattern is to light up signs and such off to the shoulder. in RHD countries the shouler of the road would be on the left... but in LHD countried like ours, the RHD kickup would actually be shining directly into oncoming traffic. my headlight are actually from taiwan which is a LHD country so i do not have the glare problem of RHD headlights fitted to a USDM car (since my set are actually LHD).

sorry took so long to reply, i just saw this. what the relay does is keep the low beams on when you put on your hi beams; this is how the JDM's were designed to work. you will need a relay for each side, passenger and driver. however if you are using full relay harnesses, you can simply use a diode to link the turn on leads from the hi beam harness to the low beam harness.


My question is do you use a relay for each side/ housing or can you use one relay for both housings? Any help is appeciated, thinks in advance!

1 relay for each housing (unless you wanna run wire from headlight to headlight). the hi beam will trigger the relay to send power to the low beam (when the stock wiring stops sending power to the low beam) but not vice versa.

Thanks relax that's what i was thinking but wanted to double check. I picked up some duel beam projectors off an audi yesterday at the pull yard and was going to do a retro fit i just was wondering before i start, so i can test out the ballist and bulbs before i start ( the lows are stock xenon hids).

Quick question. I did complete this already on my old g. But I want to know if I need to cut anything in the engine bay (near the fender, corner light). I can't remember, but I think my headlight won't fit without trimming something back there.

If one of you guys know of the top of your head, that would be awesome. Thanks.

Just some quick notes on fitment with the radiator. 1. Don't bend it, take the time and cut it, it will be much cleaner. 2. I don't know about the other Evolution radiators, but my EVO V rad clears my jdm heads perfectly. Just something to keep in mind for those that are upgrading.

PS: Keith, it's great to see you back together.

wait what did u do? since u have a relay harness for the low beams, just run a relay from one of the highs to the input wire of the low beam relay harness.

i have a burnt up h1 jdm light. I wanted to know will the usdm one connector work on my dual connectors. Or do i need to go shopping overseas for a bulb. Please help i wanted to do the jdm lights on my galant but no working h1 bulbs.

Reelax
03-18-2012, 05:52 AM
H1 bulbs are readily available in the US. they only have one connector though so the usdm H4 plug will not fit directly (not to mention you will have now have seperate low and high bulbs) so u either need the jdm adapters or you can wire a female spade connector to the high beam positive to connect to the bulb, then tap into and run the ground wire from the H4 plug (negative) to the screw that holds the clip that secures the H1 bulb to the housing (which will send ground to the bulb). mine used to be wired that way until i went full HID H7 and HID H1 (w/ HID u wire the stock wires to the ballasts (i recommend a relay harness instead of direct wiring for HID) and the bulb plugs into the ballast, so u don't need to connect the stock wires to the bulbs (which wouldn't be able to run the HID bulbs anyway).

huh? the stock bumper should fit like a stock bumper, i don't understand the problem. the only thing i can see interfering are the long mounting tabs on the bottom inside front corners of the JDM headlights themselves; those can be trimmed off if needed and some of the bumper cover can be trimmed off to allow the gap between headlights and bumper to be made smaller.

huh? the stock bumper should fit like a stock bumper, i don't understand the problem. the only thing i can see interfering are the long mounting tabs on the bottom inside front corners of the JDM headlights themselves; those can be trimmed off if needed and some of the bumper cover can be trimmed off to allow the gap between headlights and bumper to be made smaller.

Yeah that what it was needed some trimming and they panic cause they are not a custom bodyshop...They worked it out without me getting there I hope they did it good, cause bumpers are getting painted now

Anyone looking for JDM headlights, I'll be selling mine on Ebay is the next few days. I'll post the like when I do.

For the life of me, I can't seem to comprehend the diode trick. I am running H.I.D so it shouldn't burn up. I feel the Diodes will look cleaner. Do the diodes go after the stock wiring and before the ballast? What happens to the other end of the low beam wire and the and where do you wire the high beam ballast from if you use the high beam wire on one side of the diode and the low beam on the other?

The diodes go in between. So you wanna run high AND low beams at the same time when you flip your highs, and lows only. So the anode you splice into the high power wire, and the cathode you splice into
Low power wire. What you have done right there is when you turn your highs on, both low and highs get powered. Now you want just lows. So you get your power wire for the low, and solder it to the same diode, cathode side, again.

Current flows with the arrow on diodes, so when you turn your lows on, power CANNOT turn on the highs. One way valve for electricity.

I understand how it works I can't comprehend how to wire it haha.

Make sense?

Lets simplify this fellas. If 8Ga, do this:

(Jigz I hope you still have this fusebox)

Don't mind the wire under it, its for my fog trick.

Place diode this way, Viola! Lows remain with Highs. Will benefit JDM heads and the plug and play aftermarket projector lights if you are 8Ga (99-01)

And yeah, I went to go throw this together just now for pics sake. Recommended to solder, heat shrink and tuck down this connection I just threw this together for an example.
