Edsel Ranger Back Up Light Bulb Size

The Edsel Ranger back up light requires bulb sizes 1073, 1141, and P21W for the specific lighting components. Data for the bulb sizes covers the range from 1958 to 1960.

Additional Notes

The 1958 Edsel Ranger uses a P21W bulb for the back up light, which follows the ECE standard used in Europe and worldwide markets.
The 1959 Edsel Ranger uses a 1141 bulb, which follows the ANSI standard applicable to the US and Canada.
The 1960 Edsel Ranger uses a 1073 bulb, also an ANSI standard type for the US and Canada.
All three bulb types specified across the 1958-1960 Edsel Ranger share the BA15s single-contact bayonet base, meaning the physical base format is consistent across all three model years.
Despite sharing the same BA15s base, the 1073 and 1141 are not identical bulbs. The 1073 operates at 13W while the 1141 operates at 21W, making them non-interchangeable without accounting for the wattage difference.
The 1141 and P21W share the same BA15s base and both operate at 12V and 21W, though they belong to different standards bodies, ANSI and ECE respectively.
The 1073 is described as a lower wattage variant of the 1156 bulb. At 13W versus the 1156's higher output, it produces a dimmer light output under the same 12V supply.
All three bulb types are single-filament designs, which is consistent with back up light applications that require a simple on/off function rather than dual-intensity switching.
