Oh... but just wait until you test them from behind
the headlight lens; you'll be amazed at how much clarity you will lose!
Here's a snap of some "before they were behind the lens" photos (these are the Morimoto Mini D2S3.0 projectors that are currently retrofitted in my IS)...
No matter how good they look; inevitably; you're going to end up with some shadows and distorted cutoffs due to the way the lens is constructed (see below):
The pic above is looking through a brand new lens from a isX50 headlight that has never been used. Notice the blurred/ distorted parts circled in red?
Last but not least... You'll think you've solved the problem by retaining the stock IS projectors with a clear lense swap. Believe me; I went through the same thing myself:
Here's an output pic with the stock IS projectors; XB35 5K morimoto bulb and a motimoto three five ballast (this is with no plastic lens / housing in front of it):
Here's what the output was after sealing everything up:
Bottom line... DON'T GO THROUGH ALL THAT WORK FOR JUST A CLEAR LENSE SWAP. YOU WILL BE VERY DISAPPOINTED WITH THE RESULTS AND WISH THAT YOU DID A PROJECTOR SWAP LIKE I DID!
