Polaris 550 Classic Tail Light Bulb Size

Additional Notes

• The 194 bulb is the specified tail light bulb size for the Polaris 550 Classic across the 2002-2008 model years.
• The 194 bulb follows the ANSI standard recognized in both the United States and Canada, meaning it conforms to a defined set of electrical and physical specifications shared across North American markets.
• It belongs to the T10 miniature wedge form factor, a design that uses a tapered plastic base to secure the bulb directly into a socket without a separate metal cap or bayonet pins.
• The bulb operates at 12 volts, which is consistent with the standard electrical system voltage found in most powersports vehicles.
• At 3.78 watts, the 194 draws relatively low power, a characteristic typical of small indicator and tail light applications rather than high-output lighting functions.
• Because all seven listed model years share the identical 194 specification, the tail light socket design of the Polaris 550 Classic remained unchanged throughout the 2002-2008 production span.
• The T10 wedge base type is widely produced by multiple manufacturers, and any 194-designated bulb meeting the 12V, 3.78W rating is a direct fit for this application.
