Identifying LED bulbs

I want to replace the bulbs in my rv with LED bulbs. I took one of the old ones out but there is no number on the bulb. It has a flat end to it, that just pushes in and pulls out of the socket.

I looked on line but the pictures are too small to clearly identify the type of bulb I will need for replacement.

Anyone have any idea how I can find the correct replacement LED bulbs?
  • Sounds like a 921 bulb. They're very common in RVs.

    I replaced mine with ones from dx.com. They're flat panels, and just stick inside the fixture. They're a bit brighter than the bulbs, and use about 30% of the current. DX also has some smaller ones (#283830), which are a bit dimmer than the bulbs, but only draw ~16% the current.
  • Go to a store like Batteries Plus with a couple of the bulbs in question.
  • check out m4products website very helpful and if you call them they are more than happy to help you figure it out, fast shipping also , cost a little more but it is nice to have them to help you if needed . I bought all my bulbs from this company when I did all the bulbs in our fifth wheel.

  • mike-s, the ones you show appear to be what it is. Thanks. I will research from there.
