Additional Notes

The Honda Element uses the 921 bulb size across all listed model years for the back up light position.
The 2003-2006 and 2009-2011 model years all share the same 921 bulb specification.
The 921 is an ANSI-standardized bulb, meaning its specifications are governed by a recognized North American standard applicable in both the US and Canada.
The 921 bulb uses a wedge-style base, classified as T15, which refers to the tubular shape of the glass envelope at 15 eighths of an inch in width.
The bulb operates at 12 volts, consistent with standard automotive electrical systems.
At 16 watts, the 921 falls within the typical power range for reverse light applications in passenger vehicles.
The T15 wedge base design means the bulb is held in place by tension from the socket rather than a bayonet or screw mechanism, which affects how it is seated and removed.
Because the 921 is an ANSI-defined standard, aftermarket and OEM replacements from different manufacturers are generally interchangeable as long as they carry the same designation.
