Additional Notes

The Mazda CX-5 uses the DE3175 bulb size across all listed model years, spanning 2013-2023.
The DE3175 is a festoon-type bulb, meaning it is cylindrical in shape and makes electrical contact through metal caps at each end rather than through a base socket.
The DE3175 operates at 12 volts, which is standard for automotive interior lighting applications.
The 31mm length of the DE3175 is a critical fitment factor, as festoon bulbs must physically bridge the contact points of the housing, making length the primary compatibility variable.
The DE3175 designation follows ANSI standards applicable in the United States and Canada, indicating a standardized specification rather than a proprietary part.
For the 2019-2020 model years, the DE3175 specification carries a "Without LED Tail Lights" condition, indicating that trim or package configuration is a relevant factor in bulb fitment for those years.
The DE3175 is interchangeable with other festoon bulbs of the same 31mm length and end-cap contact design, provided the voltage rating and physical fit are compatible with the housing.
