Dual bi-xenon hids with separate switches

[ramharis]

Hi all,

I have a question on the dual bi-xenon setup but with a twist. My car has single lights, both high and low in the same bulb. I have installed hid bi-xenon projectors which are working just fine. I also have fog lights for which iam thinking of installing bi-xenon projectors. Fog light uses different switch.

Headlights - h4
Fog - h3

The circuit i have is, 2 separate relay harnesses one for headlights and one for fogs. Headlights are easy, just use the h4 socket to relay and high/low works. I want the fog to turn on only when i turn on the fog switch, so + and - will come from the stock fog wires to relay and the high will come from the headlight switch(split only the high signal into 2).

Questions,
1. Is that the right setup i need to make
2. With the above setup, when all the lights are off and when i flash the headlights will turn on but will the fog lights turn on as well ?

Table with my required setup

		Headlight Low	Headlight high	Fog Low	Fog high
Headlight Switch	Low Stalk	On	Off	Off	Off
	High Stalk	On	On	Off	Off
Fog Switch	Low Stalk	Off	Off	On	Off
	High Stalk	Off	Off	On	On	Since the high is connected to stalks, not sure if it would work, iam ok either way.
Flash		Off	On	Off	Off

Looks like you want your OE fog light switch to decide whether the primary (i.e. one mounted in the headlight housing) or secondary (i.e. one mounted in the foglight housing) biXenons respond to the OE low/high beam switch. Yes?

Mine is a Ford, so the light switch is on the right (RHD) Turning the knob clockwise, step 1 Parking, step 2 headlights. For the fog (calling it Step3), i need to turn on step 1 then pull the switch out.
So when i turn on the fog it should only turn on the low beam of the fog alone. But i want the high to be controlled using the headlight stalks on the steering.

I already have bixenons on the headlight (35w 4300k h1), I want to install a similar setup in fog. The only difference is, headlight power will be controlled via Step2 and fog light power controlled via Step3. Step2 and step3 can be performed independently. I can make the wiring for high beam on fog work by taking an extra lead from the h4 high beam signal, what i cannot predict is, with headlight off, would the high beam work on the fog when the headlights are off.

I'm not familiar with this style of OE switch.
With OE bulbs on the (dual filament) headlight beam and (single filament) fog beam, what happens when you turn to Step 1, pull the switch out, and turn (i.e. what you described as Step 3)? Does the low beam filament of the headlight bulb remain on at the same time as the fog light?

Also, what happens if you pull the OE high beam (I'm assuming there's a separate switch for that) while you are in Step 3? Aside from the high beam filament of the headlight bulb turning on, I assume the fog light turns off?

Just replacing the word Step to Switch, since the using the word steps is confusing.

Switch 1 - Turn clockwise - Parking Lights
Switch 2 - Turn clockwise again - Headlights (H4 single reflector for high and low- the usual)
Switch 3 - Pull the knob out a little - Fog lights

Switch 2 and Switch 3 requires Switch 1 to be performed. However Switch 2 and Switch 3 can be performed independently.
For Only OE Fog - Switch 1 and Switch 3 ( i can pull the switch to turn on the Fog)
For Only OE Headlights - Switch 1 and Switch 2.

The OE high and low beams are controlled via the steering mounted stalk.

My question is, will it be possible to use OE seeting mounted stalk for bi-xenon high and low when Switch 2 is not active.

My question is, will it be possible to use OE seeting mounted stalk for bi-xenon high and low when Switch 2 is not active.

If I understand your description correctly, I'm afraid the answer will be no.

Easiest solution is to add another switch (with 3 positions: A - off - B) and make a 3-way adjustable quad wiring.

First, buy 2 separate sets of biXenon harnesses. The input signal of 1 of the 2 can use the passenger side OE connectors, and the input signal of the 2nd can use the driver's side OE connectors. At this point, your 2 pairs of biXenon will function simultaneously (i.e. full-time quad).

Then, add 2 relays, some wiring and the A-off-B switch and modify the 2 biXenon wiring harnesses. I have a link in my signature for details.

Finally got all the equipment for the fog bixenon lights. I am setting up controls in a certain fashion. Please help validate.
My only question will be, with this setup, when the fog lights are off and i flash the headlights, will the fogs turn on ?

Just bumping the thread. Are there any issues with connecting the way in the picture ?

I have the same setup in my car. And its a RHD too.

1. Relay of Bi xenon in Headlight is connected to the OEM H4 plug, so when I flash the HL bi xenon flashes
2. Relay of the Fog Bi xenon takes the Low beam connection and negative connection from the OEM connector. Solenoid of fog bi xenon is taking connection from the HL relay solenoid connection.
3. So when i flash the shield of the fog bi xenon moves, however the ballast of the fog bi xenon is not triggered. So if your fog lamp OEM switch is on OFF and you are on high beam of flashing the headlight, the fogs dont switch on still.

Hope this helps and was what you are looking for.

I have a slight advanced set-up though as i wanted to address situation when i dont want my HL bixenon to be on high, but my fog bixenon to be on high, so added a switch and a 1 way diode to the wire going from switch to solenoid of fog and another 1 -way diode in the wire going from HL bixenon high to the fog solenoid.

Let me know if you have any more questions

Thank you. That is the setup that i was trying to achieve. Helps a lot with configuring my setup. I will get to work. Thanks again

[*]Relay of the Fog Bi xenon takes the Low beam connection and negative connection from the OEM connector. Solenoid of fog bi xenon is taking connection from the HL relay solenoid connection.

How did you make this connection. I used 2 relays with positive and negative from fog light connection and the bright i split it into 2 from the headlight h4 and connected that to the h4 fog relay. Now when i flash or turn on high beam the fogs light up too.

Fog Bi xenon relay connection of h4
Low beam - fog light positive
Ground - fog light negative
High beam - headlight high beam (created a split and used one here and one for headlight bi xenon relay)

Do i really need the second relay if iam splitting the solenoid terminal into 2 pairs of the headlight bi xenon relay ?
