Additional Notes

The Suzuki LT-F250 Ozark uses the P21/5W bulb as the specified tail light bulb size across all listed model years from 2002-2014, with the exception of 2010 and 2011, which are not present in the specifications.
The P21/5W is a dual-filament bulb, meaning it contains two separate filaments within a single glass envelope. The higher-output 21W filament typically serves the brake light function, while the lower-output 5W filament serves the running light function.
The P21/5W operates on a 12V electrical system, which is consistent with standard 12-volt automotive and powersports vehicle wiring.
The bulb uses a BAY15d bayonet base, a two-pin offset base design. The offset pin placement is intentional, as it prevents the bulb from being inserted in the wrong orientation, which would cause the two filaments to perform the incorrect functions.
The P21/5W designation follows ECE (Economic Commission for Europe) standards, indicating the bulb is recognized for use in Europe and other markets that adopt ECE regulations.
Because the BAY15d base uses offset pins, it is not interchangeable with the similarly named BA15d base, which uses symmetrically placed pins. Substituting a BA15d bulb into a BAY15d socket is not possible without modification.
