Honda Motorcycle VFR750F Interceptor Turn Signal Bulb Size
Honda Motorcycle VFR750F Interceptor front turn signal bulbs measure 1034 size, while rear turn signal bulbs measure P21W or 1073 size. The replacement chart covers vehicle production spanning 1986 to 1997.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Honda Motorcycle VFR750F Interceptor uses two distinct bulb standards across its front and rear turn signals: the ANSI standard, common in the US and Canada, and the ECE standard, used in Europe and worldwide markets.
The 1034 bulb is specified for the front turn signal across all listed model years from 1986 through 1997, making it the most consistently applied bulb in these specifications.
The 1034 is a dual-filament bulb rated at 12V and 21/5W, fitted with a BAY15d bayonet base. Its dual-filament design means it is capable of serving two lighting functions from a single housing.
The 1034 is a variant of the 1157, a widely recognized ANSI bulb. This relationship indicates a degree of design compatibility within that bulb family, though direct substitution should be confirmed against socket and wattage requirements.
The rear turn signal on the Honda Motorcycle VFR750F Interceptor does not use a single standardized bulb across all years. The P21W and 1073 types are each specified for different model years.
The P21W is an ECE-standard single-filament bulb with a BA15s bayonet base, rated at 12V and 21W. It is specified for the rear turn signal in the 1986, 1990-1991, 1993-1994, and 1996-1997 model years.
The 1073 is an ANSI-standard single-filament bulb also using a BA15s bayonet base, but rated at a lower 12V and 13W. It is specified for the rear turn signal in the 1992 and 1995 model years.
Although the P21W and 1073 share the same BA15s bayonet base type, their wattage ratings differ significantly, at 21W and 13W respectively. This difference makes them non-interchangeable despite the physical base compatibility.
The front turn signal uses a BAY15d base, while the rear turn signal uses a BA15s base. These two base types are physically distinct and are not interchangeable, as the BAY15d features offset pins to accommodate its dual-filament design.
The 1073 is noted as a lower wattage variant of the 1156, an ANSI single-filament bulb. This classification places it within the same bulb family as the 1156 but at a reduced power output.
