Honda Motorcycle VTR1000 Super Hawk Turn Signal Bulb Size
Honda Motorcycle VTR1000 Super Hawk front turn signal bulbs measure 1034 in size, while rear turn signal bulbs measure P21W or 1073, with each bulb type specified for optimal replacement. The replacement chart covers 1998 through 2005 production years and details bulb size specifications for turn signal applications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Honda Motorcycle VTR1000 Super Hawk uses two distinct bulb standards across its turn signal positions: the ANSI standard, which is common in the United States and Canada, and the ECE standard, which is used in Europe and worldwide markets.
The 1034 bulb is specified for the front turn signal across all model years from 1998-2005, making it the sole front turn signal bulb for the entire production run of this model.
The 1034 is a dual-filament bulb operating at 12V with a 21/5W output and a BAY15d bayonet base. Its dual-filament design means it is capable of serving two lighting functions, though its specific role in this application is as a turn signal.
The BAY15d base on the 1034 bulb features offset pins, which physically prevents it from being inserted in the wrong orientation. This is a deliberate design feature tied to its dual-filament construction.
The 1034 is described as a variant of the 1157, a widely used automotive bulb. The two share the same BAY15d base and dual-filament design, though they differ in wattage output.
The rear turn signal of the Honda Motorcycle VTR1000 Super Hawk uses either the P21W or the 1073 bulb depending on the model year, meaning the rear position does not have a single uniform specification across the full production run.
The P21W is a single-filament ECE-standard bulb with a BA15s bayonet base, rated at 12V and 21W. It is specified for the rear turn signal in model years 1999-2001 and 2003-2005.
The 1073 is a single-filament ANSI-standard bulb with a BA15s bayonet base, rated at 12V and 13W. It is specified for the rear turn signal in the 1998 and 2002 model years.
Although the P21W and 1073 share the same BA15s bayonet base, their wattage ratings differ significantly, at 21W and 13W respectively. This difference means the two bulbs are not interchangeable without consideration of the electrical load and intended brightness output.
The front 1034 bulb uses a BAY15d base, while the rear bulbs, whether P21W or 1073, use a BA15s base. These two base types are physically incompatible with each other, so front and rear bulbs cannot be swapped between positions.
