Additional Notes

The 57 bulb is an ANSI-standard single-filament type rated at 12V and 1W, fitted with a BA9s bayonet base. The BA9s base uses a single pin for retention and electrical contact, making it a compact format commonly found in interior lighting applications.
The DE3175 is an ANSI-standard festoon bulb with a 31mm length and end-cap contacts. Festoon bulbs make contact at both ends of the housing rather than through a base pin, which is a distinct physical configuration from the BA9s type used in the 57 bulb.
The Toyota Solara map light uses two different bulb types across the 1999-2003 model years: the 57 and the DE3175. These two types are not interchangeable due to their differing base designs and physical formats.
The 2003 model year carries a fitment note specifying the 57 bulb applies to vehicles produced up to December 2002. This indicates a mid-cycle production change occurred within that model year.
The 2001 model year uses the DE3175, while the surrounding years 2000 and 2002 use the 57. The 1999 model year also uses the DE3175, matching the 2001 fitment rather than the adjacent 2000 specification.
