Sweet. I will take my windscreen off then. Thanks.

 

No I don't. But I thought you would need a reply to switch between hi and lows

 

Just ordered a pair of H4 HID 6000K bulbs, $13.40 shipped. I think I do have a spare ballast lying around. So I hope this setup works.

 

no need for a relay, with the ddm kit it has a plug that your headlight plug goes into, then separate wires for the bulb itself.

 

For that price I assume you are going to have no Hi beams

 

High beam and low beam are the same bulb in the F4.

idealy you need a Bi-xenon H4 kit - they have a relay that moves the bulb slightly to achieve high and low beam from a single h4 fitting bulb

The bi-xenon bulbs look like this - Google Image Result for http://www.xenonsonline.com/media/catalog/product/cache/1/image/650x/68ce5aa2a896798ff2368166f05f6a0d/h/4/h4_bi_xenon.jpg

and the control box looks like this - Google Image Result for http://img.alibaba.com/wsphoto/v0/381236185/Hotsale-35W-12V-HID-BI-XENON-Conversion-Ballast-For-Moving-Series-H4-3-H13-3-9004.jpg

It has the extra connector for activating the bulb move relay.

 

I understand all that.
But there is 2 types of H4's, H4 single beam and an H4 Bi-xenon.
I am saying for the price he paid he would not be receving a Bi-xenon as it is an extra $10 (On top of the price of the bulb) to get a Bi-xenon.

Edit: Just realized your control box is a ballast which doesn't control the Hi and lo switch, You need a seperate harness to do that > http://www.ddmtuning.com/Products/High-Low-Harness

 

As people have already said - you either need 2 bulbs *with 2 ballasts*, one for Hi, and the other for Lo, or get a Hi/Lo kit.

Shameless plug

 

How do you put 2 bulbs and 2 ballasts in a F4?

 

Damn it. You guys might be right. I didn't know that there are 2 types of H4s. I bought the one says "H4-2/H 6000K Super Vision Xenon HID Vehicle White Light Headlamp (Pair)" Is didn't mention Bi-Xenon anywhere. Ah.....damn it.
