    What's difference between a 3057 and a 3057k bulb?

    My tail light burned out today. The bulb and the tail light housing say it takes a 3057k. I had a 3057 laying around and I put it in and it seems to work fine. Is there any difference between the two bulbs?

    Re: What's difference between a 3057 and a 3057k bulb?

    "K" = Krypton, a gas that can be added to the fill mix to improve bulb
    life without reducing bulb output. Some makers use "LL" instead of "K"
    (So, for instance, 3157K and 3157LL can be considered equivalent to one
    another).


    Now, output listed bright/dim:

    3057: 32/2 candlepower (also 3057K, 3057LL)

    So from what I gather, there really isn't a difference.

    As previously stated above, K or LL are extended life or "long life" bulbs. They are designed to last longer than standard bulbs.

    3057, 3057K, and 3057LL are all identical in functionality, the K and LL are simply designed to last longer.

    ^exactly as the above fellows have mentioned. In my opinion its just a scam to get you to buy the more expensive bulbs. Either buy the cheapo bulbs and call it a day or use it as an excuse to jump up to some SMD LED's for that bad boy!
