Additional Notes

The Jeep DJ6 back up light specifications cover model years 1965-1968, with two distinct bulb types used across this production span.
The 1156 is the most frequently specified bulb in these records, covering the 1966-1968 model years.
The 1156 is an ANSI-standard single-filament bulb rated at 12V and 21W, fitted with a BA15s bayonet base.
The BA15s bayonet base features a single contact pin, which is the defining characteristic of the "s" designation in the BA15s standard.
The 1965 Jeep DJ6 uses the 1073 bulb, which differs from the 1156 used in subsequent years.
The 1073 is also an ANSI-standard single-filament bulb with a BA15s bayonet base, rated at 12V and 13W, making it a lower-wattage variant of the 1156.
Although the 1073 and 1156 share the same BA15s bayonet base, their wattage ratings differ by 8W, which is a relevant fitment consideration when sourcing replacements.
The shared base type between the 1073 and 1156 does not confirm interchangeability, as the difference in wattage may affect circuit compatibility and light output in the intended application.
