Additional Notes

The Chevrolet El Camino ash tray position uses three distinct bulb types across its model years: the 1892, 1445, and 53.
The 1892 bulb is a T5 miniature wedge type rated at 12V and 3W, conforming to ANSI standards for the US and Canadian markets.
The T5 designation refers to the tubular glass envelope, which is 5/8 of an inch wide, making the 1892 a notably small-format wedge bulb.
The wedge base of the 1892 eliminates a separate metal base, as the glass pinch at the bottom of the bulb itself acts as the retention and contact mechanism.
The 1445 and 53 bulbs both share a BA9s bayonet base, a single-filament construction, 12V operation, and a 2W output, placing them in the same electrical class despite carrying different ANSI designations.
The Chevrolet El Camino (1980-1987) uses the 1892 bulb in the ash tray position, while the 1964-1973 model years use the 1445, and the 1959-1960 model years use the 53.
Because the 1445 and 53 share identical electrical ratings and the same BA9s base type, physical fitment compatibility between the two is a relevant consideration when sourcing replacements for the respective model years.
The 1892 operates at 3W, one watt higher than both the 1445 and 53, meaning it draws slightly more current and produces a marginally higher light output for the same 12V supply.
All three bulb types conform to ANSI standards applicable in both the United States and Canada, indicating standardized production tolerances and base dimensions across the listed part numbers.
The transition from the BA9s-based 1445 to the wedge-base 1892 between the 1973 and 1980 model years reflects a socket design change in the ash tray assembly, making the two bulb types non-interchangeable despite serving the same position.
