    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.

    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.
