Additional Notes

The Suzuki Motorcycle M109R Boulevard uses the 12821 bulb for its license plate position across the 2006-2009 and 2011-2014 model years.
The 12821 is a Philips part number designating a miniature wedge bulb in the T10 form factor, operating at 12 volts and rated at 5 watts.
The T10 designation refers to a tubular bulb with a nominal width of 10 millimeters, a size widely used in low-intensity automotive lighting positions such as license plate and courtesy lamps.
The W2.1x9.5d base type is a wedge-style connector, meaning the bulb is held in place by tension from the socket rather than by a bayonet or screw mechanism.
At 5 watts, the 12821 draws minimal current, which is consistent with its role in a non-illumination-critical position such as a license plate lamp.
The uniform fitment of a single bulb type across all listed model years of the M109R Boulevard indicates a stable socket specification throughout that production span.
Substituting a bulb with a different base type, such as a bayonet or festoon, would be incompatible with the W2.1x9.5d wedge socket used in this position.
Replacement bulbs carrying the T10 or W5W designation from other manufacturers are generally cross-compatible with the 12821, provided they share the same voltage, wattage, and base specification.
