Project Bi-xenon : Adding bi-xenon projectors to standard headlights-Mission Complete

[Sinan]

Hello

I have an Ibiza '10, which has single headlamp. I am driving at night mostly, so I need to see what's going on in front of me more than in day

There're couple of things to be figured out.

Problem 1
I have H4 bulbs, so both dipped and full beam is being done in same bulb. If I only buy double headlamp ones and fit them to car, I won't be able to do full beam exactly when my headlights are on (Dipped beam will be off if I push the "arm", because of H4 system structure.)

Problem 2
I found second hand double headlamp headlights. Bi-xenon projectors to be added to main beam, so what will I do with full beam halogen bulb? Here is the idea:

When headlights are OFF:

If I pull the arm full beam halogen bulb will be on, like normal headlights.
If I push the arm nothing will happen, like normal headlights.

When headlights are ON:

If I pull the arm, bi-xenon projector will switch to full beam, full beam halogen lamp won't switch on, preferably.
If I push the arm, bi-xenon projector will switch to full beam, full beam halogen lamp WILL switch on.


I need to do some wirings, and some VAG-COM job I guess.

Question is, how will I do it?

If I manage to do it, I guess I'll be the only one in world doing this

( I live in Turkey, same "MOT exam" happens here once per 2 years. I'll switch to H4 ones when I'll be at "exam", so washer jets are no problem for me. Some can disagree to do this job on a non-auto leveling system, but I don't want to dazzle people with using xenons without lenses )

Get yourself a HID Bi-xenon kit - then you have HID main and dip in the same HID kit.

No need to change from single reflector headlights

I know those, but I want to use double headlamp ones. Only projector won't fill whole headlight, it won't look good imo.

I have a mate in South Africa that I am sorting with the same xenons from the polo gti as it is not an option on them there. All he is getting is the light and the ignitors for the xenon bulbs. Fortunately they do not have these stringent testing of cars in SA so he can get away with it. We believe you can set the height of the light manually without the levellers but as you said, you will need to be swapping out headlights ever time you MOT your motor. Small sacrifice for the pleasure of stunning headlights.

 

[Sinan]

yeah, definately it is. So, what to do ?

 

[Sinan]

How does the car cuts the dipped beam off ? If the ECU controls it, then maybe I can change the value and let the car use both main and full beam without problem?

Does S COPA version have h4 or h7+h7 ? If it is h7+h7, maybe I can compare the VAG-COM values and figure it out?

edit,

as I see it has h4. I need SE COPA VAG-COM values..

 

[Sinan]

Can someone make a backup and send it to me? Any h7+h7 car is ok?

With twin headlights the car does not switch off dip beam.

If you have H7 + H7 than the car used 1 x H7 for dip and 2 x H7 for main.

If you only have H4 headlight then the bulb has Dip or low feed - not both together.

I know, I have H4 headlight now. I want to use double headlamp headlight that is H7+H7.

I need VAG-COM default values of an ibiza which has twin headlight..

 

[Sinan]

I'm sorry but.. "bump".

 

[Sinan]

up!

sure it isn't an entirely different loom?

 

[Sinan]

in my opinion, I should be able to make the ECU act like the car has main and full beam lights are seperated. My guess is VAG-COM is the way to do it, no one willing to help though.

Creating more ideas as time passes, new idea is, moving signal to high beam's place, and use signal's place for daylight, but after adding bixenon projectors, I have to move forward the signal too, otherwise projector will block it, it'll cause security problems.. Actually idea is very close to original bixenon system.

If I (have to) choose that, I won't need to edit values on VAG-COM, with just a small addition to headlight system I can use bixenon projectors flawlessly.

Moving signal and canceling full beam, using daylight instead is another option, it can be done or not, no matter. It'll look mooooore stylish, if it is done, that's it.

 

[Sinan]

switching places of full beam and indicators will cause tons of things to be done.. Because of that, I changed my mind and will use H7 daylight led bulbs.. May be I replace the indicator bulb with a led one, in future.

I would worry that modern ECUs are current sensative and whilest switching the bulb feeds about might work if you dont get the current draw accurate the ecu will think you have a bulb malfunction and cut the power.

They are pretty smart things, also im not familiar with the vag way of programming modules so dont take it as gold but surely the car just knows the difference between Dual and single lights and it would require some software from valeo or hella to get the lighting parts to reconfigure the wires.

 

[Sinan]

I doubt if my ibiza's ecu is smart, using mtec white plate light and no warning light comes on, been using it for one and a half years. I didn't check if it raises warning while plate light is taken off though, may be the bulb has correct resistance.

Even if she is that smart, finding correct current is no problem, V=I.R Adding some resistance to circuit to balance led bulb's low resistance would solve bulb failure warning issue in my opinion, never done such things before so my words are just guesses.

 

[Sinan]

Decision have been made. Bixenon projectors, powerful led daylights at full beam which will be activated with sidelights (due to darkness of dashboard in morning, my sidelights are always on) indicators will remain same. It'll be done at beginnings of november. New generation Valeo projectors will be used, if they don't fit then new generation Hellas will be used instead. d1s will be the bulb type.

Will keep you guys updated.

 

[watchboy]

Try the Decante DRL headlights. Ask them if it can fit to the fuse of a single lamp headlight. I'm not sure too. I have the same issue as you but I think I will go for a HID kit instead soon. Probably will get a Philips HID kit.

 

[Sinan]

I'm not sure quality of Dectane's projectors which will directly effect lightning ability. Plus, there will be problem with full/mean beam switch because of H4 system. They look sweet, but I want to see what's going on in front of me.

 

[Sinan]

UPDATE

Made some progress so far, projectors have been installed, decided which projector cap to use. And some more.

It'll be something like these two's sum :

and

First pic's black part plus projector fitted one

I'll be using daylight for high beam reflector place, I don't need it anymore

The projector is new generation Valeo d1s bi-xenon type. Same as cupras

Projector cap is from VW Eos. A cover which very rare here and quite expensive.

As signal, will be using Osram Diadem.

One problem is, I don't know what to use for daylight. New 508's daylight would be "PERFECT!!", but it is nearly impossible to find one second hand. Any suggestions? I'd rather choose OEM ones.
