Additional Notes

The Saturn SW1 uses the 562 bulb for the dome light across all listed model years, 1993-1999.
The 562 is an ANSI-standardized bulb, meaning its specifications are governed by a recognized North American standard applicable in both the US and Canada.
The 562 belongs to the festoon bulb category, a cylindrical form factor that seats between two spring-loaded end caps rather than inserting into a socket.
The 562 bulb has a length of 44mm, which is the critical fitment factor for festoon-style replacements, as an incorrect length will prevent proper contact with the housing.
Electrical ratings for the 562 are 12 volts and 12 watts, consistent with standard automotive low-voltage systems.
Because the 562 uses end-cap contacts, any replacement bulb must share that same contact style; a bulb with a different base type would be physically incompatible with the Saturn SW1 dome light housing.
