Additional Notes

The DE3175 is the map light bulb size for the Subaru Baja across the 2003-2004 model years.
The DE3175 follows the ANSI standard, making it the designated specification for the United States and Canada markets.
As a festoon-type bulb, the DE3175 is cylindrical in form and mounts by pressing between two spring clips at each end, rather than using a socket base.
The DE3175 has a 31mm length, which is a critical fitment factor, as festoon bulbs must physically span the housing contacts to make a proper electrical connection.
Electrical contact on the DE3175 is made through end-cap contacts, meaning the metal caps at both ends of the bulb serve as the terminals.
The DE3175 operates at 12 volts, consistent with standard automotive electrical systems.
