Honda Motorcycle SA50 Elite front and rear turn signal bulbs both utilize a 921 bulb size for replacement applications. The replacement chart covers 1988 to 2001 production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Honda Motorcycle SA50 Elite uses the 921 bulb for both its front and rear turn signals across all listed model years from 1988 to 2001.
The 921 is a wedge-base bulb, classified under the T15 designation, which refers to its tubular glass envelope size measured in eighths of an inch.
A wedge base means the bulb is held in its socket by the pinched glass base itself rather than by a separate metal cap, which is a common design in smaller motorcycle lighting applications.
The 921 bulb operates at 12 volts and draws 16 watts, placing it in the low-wattage range typical of turn signal applications on small-displacement motorcycles.
The 921 is an ANSI-standardized bulb recognized in both the United States and Canada, meaning it conforms to a defined set of electrical and physical specifications shared across manufacturers.
Because the same 921 bulb is specified for both the front and rear turn signal positions, a single bulb type serves all four turn signal housings on the SA50 Elite.
The consistent use of the 921 across the Honda Motorcycle SA50 Elite's full listed production span of 1988-2001 indicates no change in turn signal bulb specification occurred during that period.
