my trailer has the 921 bulbs in the ceiling lights . we want to replace them with the 921 base but the LED's. I found these on Amazon but the price seems awful cheap for 10 of them for 20.00 bucks. ...
I put those same ones in my trailer, and am super happy with them. I ordered both cool and warm white, and I prefer the look of the warm white bulbs, at least for the fixtures my trailer has. If I did full LED strips, then I'd probably go with cool white. I had to put the cool white bulbs in the rear bedroom (ran out of warm white) and it just feels more industrial back there, since the shadows seem harsher.
