JDM Headlight Wiring Questions

question, i bought my lude with the headlights already wired. however. the guy wired them all wierd. I know he's using the h1 an h4 bulbs, but as far as lighting goes, you may as well just call me useless. he had it set up so that when you turn on the headlights, in low beam, the outside lights light up. when you put it in high beam, the outside turns on the second filament. then he wired a separate switch altogether for the inner lights. it's not bad, but it gets annoying when you're driving at night having to swith two separate switches. so my question is, how do i wire it so that the "inners" come on with the "outers" when you turn on the high beams? like i said i don't know much about headlights and how they're wired, however, i am pretty decent at electronics. can i just snip the leads that power the inner lights and run them inline with the outer high beam lights?

also, the corner lights inside the one piece lights are missing bulbs. i'm not sure if the circuit works or not, but arent' they supposed to flash with the signal lamps?

oh and another thing, the signal lamps in the front, only the inner ones light up. isn't it supposed to alternate between the inside ones and the outside ones?
thanks in advance

Just splice the outers and inners to the same power wire.

The thing about the JDM headlights is that the driving lights are wired on JDM cars to be on 24/7 which is why its not a "direct" hookup to our cars.

ok cool. i wasn't sure if it'd be a problem because of too much current flowing throught the line. i'm at work right now so i can't check but i'll let you guys know if i run into any problems

The corner lights aren't supposed to light up when signalling IIRC.

Some people have alternating turn signals, some people have the lights come on all at once, some people have only one come on so I don't know which is which. I've had all 3 at some point in time so I don't know what to tell you

Corner lights come on when you have the headlights and/or parking lights on. I don't know about the turn signal setting from the factory since everyone seems to have different responses.

they are 168s I believe (or 164, I always get the # confused, no matter, one of those doesn't exist, so it's not a tuffy ) I haven't toyed around with my corner lamps, and they don't signal, but only come on at standby, and stay on through headlights and highbeams.
What I have heard as conflicting arguments go is true JDM application of the H4s, I used to think it was that the inners were "city" lights, and the outers were lows and highs, but I've since heard a lot of statements supporting the idea that JDMs just used one filament of the H4, and used the H1s as highs. It makes sense, because when I turned the H1s on for the first time, they were aimed higher than the H4s. It's up to you, but trust me, I was unsure of myself too when it came to wiring them, but it proved itself to be an easier job that I'd thought it would be.

Tannie, if he wires his H1s, and both filaments to one power wire, won't that be overdrawing on that wire?

umm i would cute teh harness running form the h4 into the high, and splice that into the h1., and remove his "switch".

Really i have a feeling that, the h4 bulb will burn out. the h4 bulbs on civic only use one filiment at a time, when you do that to the h4 in a jdm one peice, both are running...

so which is the h4 and h1? is there a way to make the one that has two filaments to only use one at a time? and i would like to remove the switch, but it's mounted on the dash and i'm afraid to mess it up. plus it'd be kind of stupid to have a switch on the dash that doesn't do anything

the H4s are your outer bulbs (not to be confused with corner bulbs), the H1s are the ones closest to your nose vents, on the inside of the headlight. Yeah, normally on the H4, one filament lights up (on mine, and many other's for instance), what makes the second filament light up as well is twice the power, or, for instance, wiring the high beam wire on your car's harness to the second positive wire on the bulb plug, so when you turn your regular headlights on, 1 filament lights up, then high beam, and you now have twice the power running into one bulb, which causes the second filament to light up. How does the switch look? Take a pic if you have a camera, but yeah, I know that having switches that do nothing looks bad, but I'm all for removing it. Where exactly is it located in the cabin?

If you implement relays, the low beam filament shuts off when you click on the highs.

I have mine wired so that when I flick on the highs, the h1's and the high beam filament on the h4 light up at the same time

here's a picture of the passenger and driver side light. do you guys know which is which? and what i should do? from looking at it, i know that he wired a relay inline with the switch on the dash to turn on the inner bulbs. everything else seems to be stock wiring and when you turn the lights to high beam, both the filaments in the outer lights light up. do you guys know what i should do?
thanks

passenger


driver

ok well after doing some thinking, i could run the red/green wire (assuming it's the high beam) inline with the relay so that power will only be provided when the high beams are on!

only one other problem however, what do i do about the low beams? i'll have to figure out a way to make them shut off when the high beams come on

edit: like this

wait, but then again, it doesn't really matter if all three lights are on though cause there will be almost no current draw from the relay... ahahah looks like i've solved my own problem...

ok, now i just have to make sure that the red/green is the high beams...
does this seem right to you guys?


btw, sorry for taking up so many posts.

This is how i have mine wired:

turn on headlights with switch:
turns on H4's low beams

flick for high beams:
relay turns off H4 low beams
H1's turn on
relay turns on H4's High beams

thats how i have mine setup.
