2003 headlights

[Anonymous]

Hi ALL
Sorry to be a pain  s:oops: :oops: s:oops:  but I need some more info on the headlights.

The 2003 headlights have finally arrived.

Is the extra light in the 2003 headlights, with difference to the 2002, the bright beam? Is this the wiring change that must be carried out?

Thanks

The little projector lens part is the low, dipped beam. The bigger lamp with the free-form rreflector is the main, high beam.

To fit them you need to seperate the relevant wires from your original H4 plug to power each lamp, and provide an earth connection, back to the return side of the H4 plug. Dont forget to wire in the sidelights too.

More specifically, you need to wire them differently than the old H4 wiring because with H4 bulbs, you can only have the low...OR the high beam on.  Whereas the 2003 lights are designed to keep the low beam active while the high beams are on.

In English please

Which wires go where?   s:? :? s:?

Here's my "proven" wiring diagram from my rebuild 2000 Headlights to 2003's version.......

He asks for English and gets German.  Now THAT's funny.  

The diagram is fine, but saying where the wires are located, what color they are and in laymans (novice) terms would be best.

Here's my colvoluted way of doing it...  m http://www.spyderchat.com/phpBB/viewtopic.php?t=13584 m

The wiring diagram is self explaining and the symbols added by me are in line with the German DIN standard...(that was in another thread   s:wink: :wink: s:wink:  ), having said that, this diagram also reflects the legal requirements on the European continent...no clue if the british island is different beyond driving on the wrong side...  s:lol: :lol: s:lol:

Sorry to say - this solution is only the 80% perfect one   s:lol: :lol: s:lol:  ....you can't ignore the red-green wire to ensure the indicator for the headlight in the dashboard still works. And you need a separate "ground wire" for the headlights for proper funtionality. Let me know if you have further questions - happy to help   s:wink: :wink: s:wink:

Joe, good point re: the requirement to have the low beams lit on a permanant basis. I hadn't thought of that for some reason, although I remeber doing a similar conversion on a mk5 Escort several years ago, and only needing to add one wire to achieve the correct operation.

Eifel, Thanks for your input too. Your DIN standard drawings are a great help, and its always good to work to a standard, especially in industry. But this is just a few guys fooling around with cars at the weekend, so what this guy would really like I think, is a nice simple step by step guide. Not everyone has an engineering background as I suspect you do, and something like a DIN standard electrical drawing might as well be in Dutch for all the help its going to give someone whose daily exposure to the physics of electicity is limited to which way round to put the batteries in his remote control. Perhaps you could post up a simple, understandable by everyone, step by step guide of what wire goes where, why it works, and what parts would be needed to convert the headlights?

It is self-explaining in you're an electrical engineer.  To you're average person like me and cosmos, it looks like an alien language.

As for the second part, the dash high-beam indicator (if that's what you're referring to) still works, but I don't know what you are referring to with the extra ground wire.

I'm just a poor mechanical engineer.....  s:wink: :wink: s:wink:  , but still good enough for the simple electrical stuff.....

As for the second part, the dash high-beam indicator (if that's what you're referring to) still works, but I don't know what you are referring to with the extra ground wire.

In my car, the dash high beam indicater didn't work anymore...I compared the wiring diagram of the 2003 version with my 2000 version and the sketch I've posted is the result of making the 2000 wiring work as appropriate w/ the 2003 headlights.

But - feel free to manage as you like....just my service to make it perfect.

Hi Folks,
Joined this conversation rather late, I have what was sold as a 2002 import however it has the latest 2003 headlights. Anyone know if these were fitted to the cars earlier in Japan or am too lucky to have a later car??

am too lucky to have a later car??

Actually, this is a matter of opinion... I consider myself lucky for having one of the last early cars (although I do like the facelifted headlights).

The visual differences on the facelifted version include front-fog lamps, revised headlights, revised breaklights (they are round instead of square), 16-inch rear wheels, chrome details inside, a crap stereo, seats with a "hole" at the top, revised rear and front bumpers, revised side air intakes.


Apologies for the topic drift.

Sorry to drudge up an old thread, but is there any way you can describe the diagram in layman's terms?  I've tried translating the text, but I can't seem to get the more critical phrases.   I must truly be an ignorant american  s:oops: :oops: s:oops:  

Is the 'standard' relay you refer to an SPST relay?  What do the blue wires mean?

Any help you can provide would certainly be appreciated.

Thanks!

SPST I presume means single pole single throw.

Its a way of describing a switch.


see the one in this image is a "Single Pole Double Throw"


This image is a circuit including a SPST switch.

@philster_d

Thanks for the help, but I was actually asking if the image was referring to an SPST.  It simply says 'standard relay.'  I was hoping someone could help clarify the diagram.

[kanujunkie]

dont know if this helps its the diagrams of how yours is at the mo, pre modded

thx for posting the reference.  I've already got a copy of the BGB though  s:P s:P  

Here's a copy of my post from spyderchat:

Ok, i think I've got it figured out.

I was hoping the plans were outlining a method to keep the lowbeam constant, but it appears that the relay is utilized to keep a constant 12v to the lowbeam during the switch between high/low.

This might be a dumb question, but what I need to know now is if the relay will operate quickly enough to maintain constant power to the headlight. I know there are different grades of relays for switching time, but automotive relays are relatively slow right? Is resistance an issue?

The reason I ask is that I'd like to avoid switching the headlamp on/off constantly in order to preserve the longevity of my HID bulb. If this wiring method doesn't do the trick, I think I'm better off using Joe's method...

Hopefully someone can help out?
