Additional Notes

The DE3022 is the dominant courtesy bulb type across the Toyota Tacoma for model years 1995-2000 and 2002-2004, appearing in nine of the ten listed model years.
The DE3022 is an ANSI-standardized festoon bulb rated at 12 volts, with a 31mm body length and end-cap contacts, meaning electrical contact is made at both flat ends of the bulb rather than through a base socket.
The DE3021 shares the same ANSI festoon construction as the DE3022, including the 31mm length, end-cap contact design, and 12-volt rating, but the two carry distinct part designations and are not listed as interchangeable within these specifications.
The DE3021 is specified exclusively for the 2001 Toyota Tacoma, distinguishing that model year from the surrounding years that use the DE3022.
The 13050 is an OEM/Wagner part number rather than an ANSI-standardized designation, indicating it is identified through a manufacturer-specific catalog system rather than a universal industry code.
The 13050 is classified as a halogen bulb for a specialty application, operating at 12 volts, and is specified solely for the 2003 Toyota Tacoma, setting it apart from the festoon-type bulbs used in all other listed model years.
Because the DE3021 and DE3022 carry separate designations despite sharing the same physical festoon format and voltage rating, substituting one for the other is not supported by these specifications.
