the conversion kit bulbs are different than the h11 replacement bulbs

 

Im not sure why you are confused......I ordered the H11 HID Conversion kit on accident. So it is the wrong bulb and I have reordered the right bulb and I will be waiting to get the new ones in soon!!!

 

I think this is because Nissan compromised on the combination headlight unit. I suspect that they use the exact same projector/shield/lens for both halogen and xenon lighting setups. I've got more info and pics at:

We first bought a SV/Sport that had HID's and ended up trading it in for a SV (no Sport package). We were stunned to discover that we lost the HIDs!!! Of course we viewed and test drove during the day - so who knew. By the time we found out, we had already sunk $400 on 3M film and tint.

I have since converted two '09s to HID. The first was a complete retro with TSX projectors, OEM Gen 4 ballasts, and a Philips D2S bulb and it produced much better output with a wider and sharper cut-off (especially with the plastic headlight lens off). The second conversion simply dropped in some 5000K rebased H11 bulbs with a knock-off ballasts. Surprisingly, the amount of glare was better with the Xenon conversion compared to the stock halogens, which also makes me believe that the same projector is being used for Halogen & Xenon by Nissan.

I didn't take pics of the original Nissan HID pattern or cut-off (didn't know that I would need to!), but if someone could post pics, I would be curious to see how it compares to H11 conversion pics (see above link).
