Honda Motorcycle VF500C V30 Magna Turn Signal Bulb Size
Honda Motorcycle VF500C V30 Magna front turn signal bulb size 1034 and rear turn signal bulb size 1073 are specified in this replacement chart. The chart covers 1984-1985 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 VF500C V30 Magna uses two distinct bulb types across its turn signal positions: the 1034 at the front and the 1073 at the rear, across both the 1984-1985 model years.
The 1034 is an ANSI-standard bulb recognized in the US and Canada. It operates at 12V with a dual-filament configuration rated at 21/5W, meaning one filament draws 21W and the other draws 5W.
The 1034 uses a BAY15d bayonet base. This base type features two offset pins at different heights, which physically prevents incorrect single-filament bulbs from being seated in its place.
The 1034 is a variant of the widely available 1157. While the two share the same BAY15d base and dual-filament design, they are not identical, and substitution without confirming voltage and wattage ratings carries a risk of incompatibility.
The 1073 is an ANSI-standard single-filament bulb recognized in the US and Canada. It operates at 12V and is rated at 13W.
The 1073 uses a BA15s bayonet base, which has a single pin and is not interchangeable with the BAY15d base used by the front turn signal bulb. Attempting to fit one base type into the other socket is not possible without modification.
The 1073 is a lower wattage variant of the 1156. The 1156 typically draws 21W, making the 1073 a reduced-output alternative within the same single-filament, BA15s family.
Because the front and rear turn signals on the Honda Motorcycle VF500C V30 Magna use different bulb types with different base configurations, the front and rear bulbs are not interchangeable with each other.
