Additional Notes

The 12821 is a Philips part number designating a miniature wedge bulb in the T10 form factor. It uses a W2.1x9.5d base, which is a wedge-style base that requires no locking mechanism, relying instead on tension from the socket to hold the bulb in place.
The T10 designation refers to the bulb's tubular shape, with the number indicating a width of 10 thirty-seconds of an inch. This is one of the most widely used bulb formats in automotive license plate and interior lighting applications.
The 12821 operates at 12 volts and 5 watts, which are standard low-power ratings consistent with its use in a license plate lighting position rather than a high-output application.
The Suzuki Motorcycle GSX250R uses the 12821 bulb for its license plate position across the 2018-2019 model years, indicating consistent fitment across both years without variation in socket type or wattage requirement.
The W2.1x9.5d base specification is shared across a broad range of T10 wedge bulbs from multiple manufacturers, meaning the 12821 is interchangeable with other T10 wedge bulbs carrying the same base designation, provided the voltage and wattage ratings are matched.
