Honda Motorcycle VF1100S V65 Sabre Turn Signal Bulb Size
Honda Motorcycle VF1100S V65 Sabre front turn signal bulb size 1034 and rear turn signal bulb size 1073, P21W represent the replacement specifications for this model. The chart covers 1984 to 1985 production years with corresponding bulb size data.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Honda Motorcycle VF1100S V65 Sabre uses three distinct bulb types across its turn signal positions and model years: the 1034, 1073, and P21W.
The 1034 is an ANSI-standard dual-filament bulb rated at 12V and 21/5W, fitted with a BAY15d bayonet base. Its dual-filament design makes it a variant of the more widely known 1157.
The BAY15d base used by the 1034 features offset pins, which physically prevents it from being substituted with single-filament bulbs that share a visually similar base style.
The 1034 serves as the front turn signal bulb for the Honda Motorcycle VF1100S V65 Sabre across both the 1984 and 1985 model years, indicating no change in front turn signal specification during that period.
The 1073 is an ANSI-standard single-filament bulb rated at 12V and 13W, fitted with a BA15s bayonet base. It is a lower-wattage variant of the 1156, which is typically rated at 21W.
The P21W is an ECE-standard single-filament bulb rated at 12V and 21W, also fitted with a BA15s bayonet base. The ECE standard is used in European and worldwide markets, as distinct from the ANSI standard applied in the US and Canada.
Although the 1073 and P21W share the same BA15s base type, their wattage ratings differ at 13W and 21W respectively, which means they are not direct electrical equivalents despite physical fitment compatibility.
The rear turn signal specification for the VF1100S V65 Sabre changed between model years: the 1984 model uses the P21W, while the 1985 model uses the 1073.
The shift from the P21W to the 1073 in the rear turn signal represents a reduction in bulb wattage from 21W to 13W, which affects the light output intensity of the rear signal.
The front and rear turn signal positions on the 1985 model use bulbs with different base types, the BAY15d for the front and the BA15s for the rear, making the two positions non-interchangeable.
