Additional Notes

The Toyota Paseo uses two distinct map light bulb types across its model years: the DE3423 for 1997-1998 and the 57 for 1995-1996.
The DE3423 is a festoon-style bulb measuring 41mm in length with end-cap contacts, operating at 12V. Its cylindrical form factor with contacts at each end is characteristic of interior dome and map light applications.
The 57 bulb uses a BA9s bayonet base with a single filament, rated at 12V and 1W. The BA9s base is a miniature bayonet fitting, physically incompatible with the end-cap contact design of the DE3423.
Both bulb types conform to ANSI standards applicable in the US and Canada, meaning both carry standardized electrical and physical specifications within those markets.
The DE3423 and the 57 are not interchangeable. Their base types differ fundamentally, as a festoon bulb with end-cap contacts cannot fit a socket designed for a BA9s bayonet mount, and vice versa.
Both bulbs share a 12V operating voltage, which is consistent with standard automotive electrical systems, though the 57 carries an explicit 1W power rating while the DE3423 does not share that same rating.
