Volkswagen Super Beetle front turn signal requires a 1157 bulb size while the rear turn signal uses a 1156 bulb size. The replacement chart covers 1971 to 1980 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 Volkswagen Super Beetle uses the 1157 bulb for the front turn signal across all model years from 1971-1980.
The 1157 is a dual-filament bulb, meaning it serves two lighting functions within a single housing, operating at 12V with filament ratings of 21W and 5W.
The 1157 uses a BAY15d bayonet base, which features two offset pins at different heights to prevent incorrect installation of the bulb into the socket.
The rear turn signal on the Volkswagen Super Beetle takes the 1156 bulb across all model years from 1971-1980.
The 1156 is a single-filament bulb rated at 12V and 21W, dedicated to one lighting function per socket.
The 1156 uses a BA15s bayonet base, which has two pins at equal heights, distinguishing it physically from the BAY15d base of the 1157.
Although the 1156 and 1157 share a similar bayonet-style base and the same 15mm pin spacing, their pin configurations differ, making the two bulbs non-interchangeable despite their visual similarity.
Both the 1157 and 1156 are ANSI-standardized bulbs recognized in the United States and Canada, indicating conformance to a defined set of electrical and physical specifications.
