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...

I've found they are not the same. The Chinese LED replacements for incandescent are not carefully molded to match the shape of some fixtures. I had a lot of trouble finding LED's to fit all of the standard incandescent fixtures in my rig. Most came as LED from the factory, but some closet lights and basement/UDC lights were standard. My advice is to order one LED bulb and test it.
