Additional Notes

The 194 bulb is the most frequently specified size for the Chevrolet Brookwood high beam indicator, appearing across the 1969-1970 and 1972 model years. It is an ANSI-standard miniature wedge bulb in the T10 form factor, rated at 12V and 3.78W.
The 53 bulb is specified for the 1958-1960 model years. It is an ANSI-standard single-filament bulb with a BA9s base, rated at 12V and 2W.
The 1971 model year is the sole entry specifying the 1895 bulb. This is an ANSI-standard miniature wedge bulb in the smaller T5 form factor, rated at 12V and 0.9W, making it the lowest-wattage bulb across all listed model years.
The 1961 model year specifies the 257 bulb, an ANSI-standard festoon or BA9s base instrument bulb rated at 12V and 2W.
The 194 and 1895 bulbs both use a wedge base, but they differ in form factor and wattage. The T10 194 draws 3.78W while the T5 1895 draws 0.9W, meaning the two are not interchangeable despite sharing a base style category.
The 257 and 53 bulbs share the same voltage and wattage ratings at 12V and 2W, but the 257 accommodates either a festoon or BA9s base while the 53 is strictly a BA9s single-filament type, which affects physical fitment.
All bulb sizes listed across the Brookwood high beam indicator specifications conform to ANSI standards applicable in both the United States and Canada.
Four distinct bulb types are specified across the eight listed model years, indicating that no single bulb size is a universal fit for the Brookwood high beam indicator across its full production span.
