Additional Notes

The 562 bulb follows the ANSI standard, making it the applicable specification for the United States and Canadian markets.
The 562 is a festoon-type bulb, which means it is cylindrical in shape and makes electrical contact through metal caps at each end rather than through a base socket.
The Saturn SC uses the 562 bulb for the dome light across its 1991-1992 model years.
The 562 bulb has a 44mm length, which is the critical fitment factor for festoon bulbs, as the end-cap contacts must span the fixture's mounting points precisely.
The 562 operates at 12 volts and 12 watts, consistent with standard automotive low-voltage electrical systems.
