I'm just learning about HID and retro'ing so this is a definite noob question - I was wondering what the difference's are between a reflector bowl and a HID based bowl (mainly the shroud that sit's in front of the bulb) or is it on the backing lens that is reflecting the light that makes the difference in the light pattern ? I want to set up some HID's in my stock Halogen housings. oh yeah, I have a 2002 Subaru Legacy.
to get started on the electrical portion I am going to run the relay harness, and mount the ballast to a set of D2R's in my Halogen stock lamps so at least I have the wiring and HID completed.
What I am wondering is if I can modify the beam pattern some how in my stock housings, and would I be okay, or is it going to be scattered,and illuminating everywhere. I'm in the process of accumulating the necessary parts to attempt my first retro using some FXR projectors into a stock Legacy housing, but that will probably be in the near future. Any information is greatly appreciated, like I said I'm just learning about HID after weeks of reading through this forum's postings.
