OK, I never thought I would ask about light bulbs. I had a bulb go out in the bathroom. The lamp says 18v type 921. Searching online at large stores, the closest I get is a T5. Is this a match? Pic of the lightbulb and light fixture.
Replace it with a t10 led.
T10 is about as common as common gets.
It's just a bulb.
T10 denotes the base and blade.
Sounds like a plan thanks!
Note... replace all three, then they'll match!!
The picture given looks like these are brighter than what my Mazda truck headlights are! :ermm:
