Additional Notes

The Chevrolet El Camino glove box uses three distinct bulb types across its production span: the 1895, the 1893, and the 257.
The 1895 is a T5 miniature wedge bulb rated at 12V and 0.9W under the ANSI standard applicable in the US and Canada. It is the most frequently specified bulb across the El Camino glove box fitment data, covering the 1964-1973 and 1978-1987 model years.
The 1893 is also a T5 miniature wedge bulb operating at 12V, but it carries a higher wattage rating of 2W compared to the 1895. It is specified for the 1974-1976 model years.
Although the 1895 and 1893 share the same T5 wedge form factor and voltage rating, their wattage values differ. The 1893 draws more than twice the power of the 1895, which means the two are not electrically identical despite their physical similarity.
The 257 is specified for the 1959-1960 Chevrolet El Camino and differs fundamentally from the wedge-type bulbs used in later years. It is a 12V, 2W bulb available in either a festoon configuration or a BA9s bayonet base, representing a different mounting and contact system entirely.
The physical and base-type differences between the 257 and the T5 wedge bulbs mean the two groups are not interchangeable, as each requires a socket designed for its specific base type.
