[al51603]

Hello
I have a bmw 525i 2002 and my low beam is a h7 factory bulbs but i want to upgrade to H.I.D.

But i dont know what HID kit to buy, i dont know if it is the same that h7 factory bulb, because the base between h7 halogen bulb and h7 HID bulb is different and I dont know if the hid bulb is going to fit.

thank you.

i would thank any help

go on ebay and search for "BMW" and "Xenon". You'll get a few choices of real xenon bulbs that will fit.

www.umnitza.com sells an H7 HID kit, i have it in my E39. TC535i on here sells the kits, PM him.

Wow... only $850 for a complete set of OE HID for E39?

I want to buy the hid, but as it is a little expensive, I want to be 100% sure that is going to fit in my 525i 2002 BMW, please take a look to my picture.

1. Is my factory h7 bulb

2. this brown thing is where i need to put my h7 bulb

3. Here i insert the bulb

4. This is how my h7 bulb looks attached to this brown
thing, and now that is compete, i put the brown thing
with the h7 bulb inside the low beam projector.

But my question is: How does the H7 HID BULB in
picture 5 is going to fit in the brown thing in number
2 ?

I would thank any help.

LOL.


You need the ballast and ignitor buddy.

I wasn't going to stop him until I saw his nitrous setup, or something equally as dangerous.

Thanks liquidtiger720. I already know that I need the ballast and ignition, but I guess I need to install the HID BULB into the brown switch (pic 2) , then to can fit in the low beam projector. But i think it is not going to fit.

Thanks

You'll most likely need to rewire.

You are better off buying whole new HID headlight... sell your old headlight and the cost is close enough to just the bulbs.

The problem is going to be moisture because of that brown thing cannot be used with HID retrofit and you got no tight seal.
