American Motors Rebel front and rear turn signal bulbs utilized 1157 and 1034 bulb sizes across the vehicle's production span. The replacement chart documents bulb size specifications covering 1958 to 1970.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The American Motors Rebel uses the 1157 bulb for both front and rear turn signals across the 1966-1970 model years.
The 1034 bulb serves both front and rear turn signal positions on the Rebel for the 1958-1961 model years.
The 1157 is a dual-filament bulb operating at 12V with a 21W/5W output, mounted on a BAY15d bayonet base, and is recognized under ANSI standards in the US and Canada.
The 1034 shares the same BAY15d bayonet base and 12V, 21W/5W electrical rating as the 1157, and is classified as a variant of that bulb under the same ANSI framework.
Despite the physical and electrical similarities between the 1034 and 1157, they are distinct ANSI part numbers, and substitution between them warrants attention to fitment compatibility for the specific model year of the Rebel in question.
The dual-filament design of both bulbs allows a single unit to serve two lighting functions, with the higher wattage filament (21W) typically handling the turn signal flash and the lower wattage filament (5W) handling a secondary function such as a running or parking light.
The BAY15d bayonet base found on both the 1157 and 1034 features two offset pins, which physically prevent incorrect rotational installation and ensure consistent filament alignment within the socket.
The front and rear turn signal positions on the American Motors Rebel use identical bulb specifications within each era, meaning the same bulb type fits both locations for a given model year.
