Thread: My HIDs

I got my HIDs from DDM tuning (google is your friend, but it's something like https://www.ddmtuning.com )

-don't want to look up your specific bulb type, but just use the same bulb type that came factory and you should be just fine, since all you are doing is replacing the bulb and adding a ballast behind it (but it's got about a foot of wire so you can put it anywhere you need to). Get the upgraded harness, it makes life simple, and causes no harm. I'm very happy with my HIDs, especially since they have a lifetime warranty on the bulbs and wiring.

-from what I've read 04+ can't disable the DRLs.... I don't know 100% though. Also not sure what effects that will have on the HIDs, just know that it's not good and may (should) shorten the life of the bulb and/or ballast.

good luck!

If I were to order the kit from DDMTuning, the relay harness is this, correct?

HID Kits, BMW Aftermarket Bumpers & Lighting, DEPO - DDM Tuning

yeah, that looks right.

Also, they are on sale again. I got mine last time they were on sale and it took 2-3 weeks to get here because they had so many orders they ran out and they were on back order. Worth the wait though! If you have questions you can always call them. They answered all my questions.

i don't think you can for 04+

For those of you who are already running HID's, are any of you running relay kits? I heard those are needed to protect the components?

ya im running one. i think they help protect the hids from sudden hits of power to protect the bulbs and ballasts.

like the key fob useage, but you should have already turned the headlight flash off.

If you order the DDM HID hi/HID low bulbs, it comes with the relay kit.... but the hi beams don't really work.... then again, they don't have to and I haven't needed them since. I drive for long distances at night in the middle of nowhere, and everyone else has their hi beams on.

I tried googling for more info on these and all I really found was debates as to whether or not they're really necessary.

What do they do exactly? How do they connect into the system? Can you just get any ol relay kit from anywhere and use it with any HID's?

Sorry for the dumb questions, I really did try to find answers first.

Ballast just zip ties to the car you are thinking too hard

I don't know about the voltage regulat though. Mine haven't melted anything.
