Austin Mini Moke front turn signal bulbs measure 1034 in size while rear turn signal bulbs measure 1073, with each bulb type serving distinct lighting functions on the vehicle. The replacement chart covers 1964 through 1966 production years and documents 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 Austin Mini Moke uses two distinct bulb types across its turn signal positions for the 1964-1966 model years: the 1034 at the front and the 1073 at the rear.
The 1034 is an ANSI-standard bulb recognized in the US and Canada. It operates on a 12V system and carries a dual-filament design rated at 21/5W, meaning one filament handles a higher load while the other handles a lower one.
The 1034 uses a BAY15d bayonet base. The offset pins of the BAY15d base are a physical safeguard against incorrect installation, as the asymmetric pin placement allows the socket to accept the bulb in only one orientation.
The 1034 is described as a variant of the 1157, a widely used automotive bulb. This relationship indicates shared electrical and physical characteristics, though the two are not necessarily interchangeable without confirming exact specifications against the application.
The 1073 is also an ANSI-standard bulb recognized in the US and Canada. It is a single-filament bulb rated at 12V and 13W, serving a dedicated switching function at the rear turn signal position.
The 1073 uses a BA15s bayonet base. Unlike the BAY15d, the BA15s base features symmetrically placed pins, which is consistent with single-filament bulbs where polarity orientation is less critical.
The 1073 is described as a lower wattage variant of the 1156. The 1156 is a common single-filament automotive bulb, and the 1073 draws less power while sharing the same base type.
Because the front 1034 and rear 1073 use different base types, BAY15d and BA15s respectively, the two bulbs are not physically interchangeable with each other in the Austin Mini Moke (1964-1966).
