Lighting/bulb question

Are all 921 bulbs the same? I know our 5th wheel uses 921 bulbs, it's stamped on one of the bulbs I took out to look at. And I'm looking to replace my 921 incandescent bulbs with LED's and found these: https://www.superbrightleds.com/moreinfo/miniature-wedge-base/921-led-bulb-12-wide-angle-led-mini-wedge-base/203/ I just want to make sure they'll fit the same before I buy them. Or if anyone knows where some better, brighter ones are please post a link. I need 18 of them.

    Yes it will fit, if it does not light then turn the LED replacement 180°, as the LED are polarity sensitive. :)


    Okay awesome! Thank y'all :)

    What I meant by that part was, would a 921 LED fit into a regular 921 incandescent?
  • As far as LEDs go, no. the base is the same, but some are designed for all around light, some are designed to go in a directional lamp, whatever. Depending on your particular lamps, you may need the ones that direct light to the sides, or all round instead of just the ends. Consider you fixtures, and select ones that will work best.
