What replacement bulbs am I looking for?

Hey forum,

My girlfriend and I have are living in a 33ft Nomad Travel Trailer. I believe the year is 1988. I have attached a photo for reference. We bought the trailer a few months ago and renovated the inside and all is pretty good so far, however we need to replace all of the interior lights now and I'm not sure what bulb type I am looking for.



We are currently getting out electricity from 400w of solar panels so I'm hoping to get some LED's in there.

Any tips in the right direction would be great.

    The fixtures look like plastic so I suspect the bubs are 1141 bulbs. 1156 bulbs get even hotter than the 1141s and can cause damage to plastic fixtures. Mine had 1141 bulbs.

    I replaced most of my 1141s with 36-1210 warm white LED panels.

    These are the panels I used.

    I also used some 18-5050 cob lights but I don't remember who the vender was.

    There are considerable differences between lights sold by different venders so buy a couple and see how you like them before buying a lot of them

    There are a variety of LED choices that will directly replace those bulbs. The Asian E Bay sellers will have the cheapest offerings. I replaced all of my 1141's with either SMD 36-3528 or SMD 48-3528 LED flat panels in warm white. I could have purchased them with the base adaptors to plug in but chose to replace the fixtures as well.

    Here is one of my DIY fixtures with one of these LED panels, cost was less than $4, inclusive:

    Here are some pictures.


    That is either an 1141 or 1156 with the 1141 drawing 1.44A and the brighter 1156 drawing 2.1A. Not sure what that fixture is rated for so try the 1141 first. Better yet measure one or several of the existing bulbs and see what the resistance is.

    Here are the specs:

    My guess is an 1141 or 1156 bulb, but without a photo off the bulb it is only a wild guess. These are both single contact bayonet base If you have a wedge base they could be 911 bulbs.

    Lots of LED conversion threads here.

    Could be one or more of several types. Can you post a photo of the bulbs. They typically are marked on the metal base assuming you have that type.

    There are a number of threads on here about upgrading to LED bulbs. Most are very happy with the results. With solar power, the difference in power used will be significant. It is a bit costly, but probably worth it.
