Honda Motorcycle VF700C Magna Turn Signal Bulb Size
Honda Motorcycle VF700C Magna front turn signal bulbs measure 1034 in size, while rear turn signal bulbs measure P21W in size. The replacement chart covers 1984 to 1987 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 VF700C Magna uses two distinct bulb types across its turn signal positions, with the front and rear positions each requiring a different bulb for all model years 1984-1987.
The front turn signal on the VF700C Magna takes the 1034 bulb across all four model years covered in the specifications.
The 1034 is a dual-filament bulb operating at 12V with a 21/5W output, meaning its two filaments draw different wattages for separate lighting functions.
The 1034 bulb uses a BAY15d bayonet base, which is an offset-pin base designed to prevent incorrect installation by ensuring the bulb can only be seated in one orientation.
The 1034 is classified under the ANSI standard, making it the format used in the United States and Canada markets.
The 1034 is a variant of the 1157 bulb, though the two are not necessarily interchangeable despite their close relationship, as variants within this family can differ in voltage, wattage, or base pin offset.
The rear turn signal on the VF700C Magna takes the P21W bulb across all four model years covered in the specifications.
The P21W is a single-filament bulb rated at 12V and 21W, classified under the ECE standard used in Europe and internationally.
The P21W uses a BA15s bayonet base, which is a single-pin base and is not compatible with the BAY15d dual-offset-pin base used by the front 1034 bulb.
Because the front and rear turn signals use bulbs from different international standards with different base types, the 1034 and P21W are not interchangeable with each other.
