Additional Notes

The Toyota Tacoma uses the DE3175 bulb size for the trunk across all listed model years from 1995 to 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 automotive electrical systems.
The festoon bulb has a length of 31mm, which is a defining fitment factor. Installing a festoon bulb of a different length, such as a 28mm or 36mm unit, would result in an improper fit within the Toyota Tacoma's trunk light housing.
The DE3175 designation follows ANSI standards, meaning it is a specification recognized across the United States and Canada, and bulbs sold under this designation from different manufacturers are expected to share the same physical and electrical characteristics.
Because the DE3175 specification remained unchanged across all 21 listed model years of the Toyota Tacoma, a single bulb type covers the full 1995-2015 production span represented in these specifications.
