What brand bulbs are in the USDM STi? Just wondering if swapping to another brand of OEM D2R bulbs will change the color output. I've heard the Osram is a bit diff then Phillips and so on.
Also what would happen if you put OEM D2S bulbs in reflector housings? I think they would put out more light but would there be a bad glare? I have some spare bulbs so I was thinking I might try them and see what happens.
