d2r = OE HID reflector housings.
d2s = OE HID projectors.

I'm not an expert, but I bet the standard "it's different," is the answer. The source of the light in relation to the base is different from halogens to HIDs. The manufacturers of OE reflectors that use HIDs take the difference into account when designing the shape of the reflector.

Our reflectors are designed to use light from a certain location effectively and when you move the location of the source (switching to HID bulbs) you change the way the reflectors reflect which leads to glare (light going in a direction it's not supposed to).

Sound reasonable?

i had D1R (thats the bulbs with the ignitor together) and they had the ceramic strip, i had them mounted with a custom bracket, the cutoff was just as bad as aftermarket HID kits, so no help in that perspective, remember the the glare made by HID kits comes from light reflecting from the bottom to the top, whereas the ceramic coating is on the top of the bulb rendering it useless, the only benefit from this would be quality! that is if the rebase was done right , littlechongchong lights could suck

I had some D2R bulbs rebased from www.hidexpert.com (4300K OEM Lexus bulbs) to a 9006 and they came out pretty good, I'm satisfied with them. Cutoff isn't perfect, obvisouly, but not too bad, adjusted the beam down some so it wasn't too blinding and get very few high beams from others. Can't think of his name off the top of my head but the guy was really helpful, got them back pretty quickly, no complaints. But definately want to start with a D2R bulb not D2S for the coating. And for only $35 pretty good deal.

Actually, with a properly rebased bulb, the light source will be exactly in the same position. The length of the discharge arc (3-4mm) is also comparable to that of the 9006 filament. The problem is that most (if not all) rebased bulbs are not aligned.

As for the ceramic coating, I always thought it would be on the lower side of the bulb, otherwise I agree it would be completely useless. I've never seen one in person, so I can't say for sure.

I found at least one person on this forum who has these kind of bulbs, it would be great if you could share the results.

How about the glare? Could you keep the OEM glare shield, did the bulb fit without removing it?

oem glare shied is useless with hid bulbs, the only way i see is if some company acctually did some R&D and made some hid bulbs with ceramic coating in the right places to prevent exessive gare, like i stated before, the cermic coating on the top of the hid bulb is useless (this is a really good idea by the way for a company with the resources to do this)

Reflectors are made with two prototypes:
A) Reflective based Halogen:
B) Reflective based High Intensity Discharge

Difference?
The little rhombus or square things on the halogen reflective setup are bigger. I call them gills like the fish gills u know,
Also, the bottom of the reflective setup is different which causes no glare and an actual cutoff.

I would try to retrofit Prius reflectors in our housings, but space is a problem.
And HID reflector retrofits have been done...just not on tCs...more on 6th gen Civics or other cars with large enough headlight housings.

BSP - Glare is not all that bad like I said before, I get very few high beams from the oppposite traffic, but since I adjusted the beams down a little that it even rarer. Bulb fit fine, not fitment problems. I had wanted to get another shield (since I have clear corners to put in) and put them in but it's a matter of finding one that fits too. I'm pretty certain that if you reomved the shield the beam would be all over the place.

i think if you are capable of doin a reflector swap, then u are more then capable of doin a projector retro, with makes reflector swapping a moot point

BTW, D2R bulbs run at 2800 lumens. That's 400 less than the 85122 and 600 less than a 85122+ . Halogen output is 600-1000 lumens.
There will always be glare no matter what you do, due to the design of the reflective halogen to begin with. That's why most of you when the car was new and had halogens, you could clearly see some ghost spots above the cutoff.

w0w, i just saw a mustang with eBay projectors and 10k HID. Past right by a cop that was about 2 cars behind me and got nothing, freaking pig! Dude was blinding the sh*t out of everyone! You could see the glare honestly about 500ft away (long street). goes to show why i hate PnP HID kits in any housings!

chicotunner07

only thing worse than glaring HIDs is a lifted redneck truck with glaring HIDs

now that is blinding as hell!!!

While we're on the subject of HID's I have Lexus OEM D2S bulbs ballasts that are going to be up for sale need to post them up in the right section, perfect for rebasing ($35 - www.hidexpert.com) for '08 or aftermarket projectors if anyone is interested. 4300K by the way...

post them on HIDPlanet.com and im sure they'll sell fast.
