Additional Notes

The Saturn L200 uses the 561 bulb for the dome light across the 2001-2003 model years.
The 561 is an ANSI-standardized bulb type, meaning its specifications are governed by a formal industry standard recognized in both the United States and Canada.
The 561 is a festoon-style bulb, which is a cylindrical lamp that makes electrical contact through metal caps at each end rather than through a base socket.
The bulb measures 44mm in length, which is the critical fitment factor for festoon bulbs, as the housing span must match this figure for proper contact.
The 561 operates at 12 volts and draws 12 watts, consistent with standard automotive low-voltage electrical systems.
Because festoon bulbs rely on end-cap contact rather than a keyed base, substitution with another festoon bulb requires an exact length match of 44mm to ensure secure seating in the Saturn L200 dome light housing.
