DDM Tuning HID's $30!
First the plug n play issue people are having.. i keep reading about setting Present to Xenon? whats this about, is it just a setting on the cars display or how do you go about doing that?
and second, basically if i've had no real experience with wiring electrical ballasts/sockets/anything of the sort, what would i be looking at trying to install this myself? a days work and then a broken headlight? or is this soemthing that's pretty doable with a few instructions and pictures? or would i be better off bringing it in somewhere in the first place, and if that's the case what should i be looking at on installation costs? (i'd probably get a closer estimate actually calling a shop lol but any help is appreciated)
edit: and this one makes me feel real dumb but
Thanks alot for any answers on those!

and someone mentioned that it gave an error on pre-facelift models (which i'm assuming is before 05?) I've got an 03, can anyone confirm that i'll have errors or not?



There are some questions you need to ask any one that sells kits to convert to HID lamps:
Is the conversion beam pattern correct?
How is the conversion made to be beam pattern correct?
How is the conversion tested to ensure beam pattern correctness?
If it is not beam pattern correct, can they tell you how to fix it?
Do they know what a correct beam pattern looks like?
Are they aware that non-beam pattern correct conversions have serious disadvantages? A person could get hurt!
I can't see how a bulb designed for a projector housing can be installed in a reflector housing and get a proper beam. Since the lamps must have their base changed, it might be possible. Mid 90's Mercedes actually had such a lamp, but it has fallen from favor. One big problem with putting a HID lamp in a reflector is the insulation of the return wire. Most reflectors are metalized, and will arc to the return wire.
The color temperature of the lamp is either 4300K or 6000K. The metallic salts in the bulb determine the color temperature. Only 4300K is used in OEM headlights. How would you measure it? Knowing that most people can't, sellers lie. The way they make it blue is to put a filter on the external glass. This raises the color temperatue, but decreases the light output significantly.
My experience is that Osram (Sylvania) or Philips HID bulbs get more blue as they age, and they last about 2,000 hours. Asian lamps (unknown manufacturer) seem to remain rather constant in color, but expire at about 200 to 600 hours.
Conversion to Bi-Xenon is possible, but you must change the housings. MbenzNL.com has more infomation on factory parts.
My HID kit came today! It took me quite a while, but after a trip to the hardware store (well, two of them) to get a unibit do drill holes in the dust covers, I got them installed. I had to use the error eliminators, though; I installed without them, which worked until I turned on the car, then flickering and bulb out error. I went for a test drive, re-aimed my headlights a bit, and now everything is great. I had trouble figuring out where to place the ballasts. I need to be able to drive the car, so I used the adhesive (for now), but used the small zip ties that came with the kit so that, if the adhesive fails before I can fix their placement, they will keep the ballasts around. If the adhesive fails, the ballasts will be hanging from tubing.

great kit, totally PNP with relays wired in-line, NO ERRORS, NO FLICKERING.
A little more than most kits, but seems pretty high quality, 112.00 out the door.
sorry i'm noob at this hid install cause i came from an import and we don't need any eliminators
They are the 55w 6000k DDM slim ballast kit. I am absolutely astounded at how great these are. They are in the stock halogen housings (H7 bulbs) with error eliminators. Also, just the low beams. One thing that I have noticed with these is that the cutoff goes up alot on the right (for signs and such), but just at dusk, highway signs light up amazingly.
