    They don't work on dim at all. Standard lights, not HID. They do work on high.

    Strong chance they're just burnt out.

    One probably went a while ago without telling anyone, and now the second one has joined it.

    Don't feel bad, it happens pretty often.

    They're Silverstars only a few months old.

    hmm those don't usually last as long as normal ones, but they usually last longer than "months."

    Time to bust out a voltmeter and start checking, I guess.

    Will the high and low relays swap for testing?

    ChapmanF says, "no," in the other where you're post the same line of enquiry.
