    It is a nifty technology. The GE and Toshiba versions were not very good. The current-production Philips items are quite good.

    it is unfortunate the technology is limited to 9011/9012 fitments (9005/9006).
    9011 and 9012 are not the same as 9005 and 9006. They are physically and optically compatible (9011 for 9005 and 9012 for 9006) with minor base modifications as you know, but it is definitely not the case that a 9012 can be installed safely in every/any 9006 lamp.


    In my old 2008 Mazdaspeed3, I couldn't get the old style Toshiba 9012 HIR in the fog lamp housing.
    That's good -- 9012 bulbs are not appropriate or safe for use in most fog lamps; the nearly 90% increase in intensity means very dangerous levels of glare no matter how you aim the lamps.

    As a general rule, HIRs are not OK to use in reflector-type fog lamps designed for 9006 bulbs. They work OK in some projector-type fog lamps designed for 9006 bulbs.

    it can't hurt to try
    But yes, it can, unless you have the expertise and equipment necessary to assess the level of glare produced by your retrofitted fog lamps.

    there were no glare issues in the Mazda fogs with these bulbs
    Yes, there were. You have just proved my point by claiming, without basis, that they were fine. I had those particular fog lamps in mind when I said "No" the first time in this thread.

    honestly, they were relatively poor from the start in terms of a fog pattern and were probably more for aesthetics
    Yes, and this is one of the reasons why making them 90% brighter with your bulb swap was not a safe thing to do.

    i used them more as another illuminated light on the front of my car for other drivers than anything else.
    That is not an appropriate, safe, or legal use of fog lamps.

    all it did was make a brighter glow on the bottom of my bumper in terms of oncoming drivers.
    That is a pretty fancy way of saying "more glare".

    i rationalized the waste of money on a slightly increased safety factor.
    There was no increased safety factor. Your modification reduced safety both for yourself and for the other drivers on the road with you. This exact kind of situation (deciding it's "better" or "safer" based on no real understanding of the matter -- or just because one might want to believe it's better) is why lighting standards and regulations are based on objective measurements and not on subjective guesses.
