Are C921 and 921 Bulbs the Same

Published 11/13/2023

Question:

Recently I picked up led bulbs to replace incandescents that I have in a 30 year old Jayco camper. The old bulbs are c921. Even though I was told that the led 921 would be an exact match, they do not fit. There must be a distinct difference between c921 and 921. Do you carry the led exact match for the c921 incandescent?

C921 and 921 bulbs are the same fit so what you have should fit. The difference is the C921 is supposed to be just a little brighter. If you can't get your 921 bulb to fit you might check to make sure your old bulb is a 921.
