Additional Notes

The DE3175 is the dome light bulb size specified for the Nissan TITAN across the 2004-2019 model years covered in these specifications, with the exception of 2016, which is not present in the data.
The DE3175 follows the ANSI standard, meaning it conforms to a recognized North American specification used in both the United States and Canada.
The DE3175 is a festoon-type bulb, a form factor defined by a cylindrical body with metal end-cap contacts at each end rather than a base or pin configuration.
The 31mm length in the DE3175 designation refers to the distance between the two end-cap contacts, which is the critical fitment factor for festoon bulbs in a spring-loaded holder.
The DE3175 operates at 12 volts, consistent with the standard electrical system voltage found in conventional passenger vehicles and light trucks.
Because festoon bulbs are held in place by spring tension against their end caps, the 31mm contact-to-contact length must be matched precisely for the bulb to seat correctly in the Nissan TITAN dome light housing.
The "DE" prefix in the DE3175 designation identifies it as a double-ended festoon bulb, distinguishing it from single-contact or wedge-base interior bulbs that are not interchangeable with this fitment.
