I'm not poo pooing the HID's - I wish the LC had them. The DDM stuff may be of good quality no dispute here. You are simply using a reflector housing that is not optimal for the bulb as you said "good enough". But for me Good enough doesn't cut it.

But it cuts it better than HIRs . If cutoff is the same and testing both yields similar results to oncoming motorists, what is left to dispute?
RobRed said:I would agree with anthonycds' comments. The reflector properties in the LC cannot present the HiD in the proper aspect/orientation. You get very bright light. If that's good enough, then enjoy. But to the original poster he didn't want hid and thus hir was suggested.
My Allroad Quattro had some of the best performing hids around so I'm sorry if I use them as a benchmark for good quality headlights. I really wanted to put hid in the LC but unless one is prepared to spend on a lamp/projector retrofit to do it properly you're wasting lumens.
Other way around in terms of part numbers... I went low beam only, HIR2 9012. Yes the upper tab needs to be trimmed.
I was under the impression that the "real" HIRs had a fatter bulb with a reflective coating, hence the "halogen infared reflector" designation. If it's a regular shaped bulb, I don't think it's the real deal man. I could be wrong though.
You can't go wrong ordering them from here: HIR Headlights 9011 9012 bulbs
First Pfran your subjective response is right on. I'm certainly not telling you you are holding it wrong. But you could be holding it better.
Subjectively looking at light output it reminds me of comparing speakers... to a human brain the perception of a better speaker is often which one is louder. I spent years working in the audio industry and invariably that was the perception in double blind testing. I think we are in the same arena with talking about these head lamps... one of the issues with lighting, anthonycds mentioned/alluded to this is the quality of the light. Brightness is not quality.
HID lamps have been designed to operate with specific characteristics including very controlled outputs (focus) and cutoffs, primary and secondary (scatter). These design elements reduce the drivers vision fatigue as well as improve off axis retina transition, that is moving your point of visual processing from the headlamp field of projection to surrounding areas. When using a lamp that is not in a properly designed housing/reflector you are actually reducing your visual capability. Sure it seems better because bright equals better in subjective viewing but you are are actually hurting your critical vision and your ability to distinguish objects depth of field (reduced contrast ratio). This is most pronounced in your peripheral and long distance vision (beyond the primary headlamp projection). These two effected areas are critical safety considerations, particularly at highway speeds of say 60mph (88ft /sec). In a properly designed HID lamp the transition between primary and secondary (scatter) illumination zones is much more controlled and the rods in your retina can make adjustments and distinctions more quickly.
In the end this is academic. I know you're enjoying your HIDs as well as many others and I'm not trying to talk you out of it. But lets be honest... unless you are doing a proper lamp/reflector conversion it's just a hack.
