Additional Notes

The Honda Crosstour uses the DE3175 bulb for its dome light across all documented model years, spanning 2012-2015.
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 consistent with standard 12V automotive electrical systems.
The 31mm length of the DE3175 is a critical fitment factor, as festoon bulbs must physically span the contact points of the housing to seat correctly.
The DE3175 designation follows ANSI standards, indicating the bulb meets defined specifications recognized across the United States and Canada.
Because the DE3175 is an ANSI-standardized part, equivalent bulbs from different manufacturers sharing the same designation are generally interchangeable, provided the 31mm length and end-cap contact design are maintained.
