Honda Motorcycle VF700S Sabre Turn Signal Bulb Size
Honda Motorcycle VF700S Sabre front turn signal bulb operates at 1034 size while rear turn signal bulb utilizes 1073 and P21W sizes. Replacement chart covers 1984 to 1985 production years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Honda Motorcycle VF700S Sabre uses three distinct bulb types across its turn signal positions: the 1034, 1073, and P21W.
The 1034 is a dual-filament bulb rated at 12V and 21/5W, fitted with a BAY15d bayonet base, and is classified under the ANSI standard applicable in the US and Canada. It functions as a variant of the 1157.
The 1073 is a single-filament bulb rated at 12V and 13W, fitted with a BA15s bayonet base, and is also an ANSI standard type. It operates as a lower wattage variant of the 1156.
The P21W is a single-filament signalling bulb rated at 12V and 21W, fitted with a BA15s bayonet base, and follows the ECE standard used in Europe and worldwide markets.
The front turn signal position on the Honda Motorcycle VF700S Sabre uses the 1034 bulb for both 1984 and 1985 model years.
The rear turn signal position differs between model years. The 1985 model uses the 1073, while the 1984 model uses the P21W.
Although the 1073 and P21W share the same BA15s bayonet base, they are not interchangeable. The 1073 is rated at 13W while the P21W is rated at 21W, representing a significant wattage difference that affects electrical load and light output.
The BAY15d base of the 1034 is physically distinct from the BA15s base of both the 1073 and P21W. The BAY15d base features offset locating pins to accommodate its dual-filament design, making cross-substitution with BA15s bulbs mechanically incompatible.
The 1034 and 1073 follow ANSI standards, while the P21W follows ECE standards, reflecting a difference in regional specification frameworks between the 1984 and 1985 rear turn signal fitments.
The dual-filament design of the 1034 front turn signal bulb means it serves more than one lighting function through separate filaments operating at different wattages, 21W and 5W respectively.
