Additional Notes

The 1987-1988 Pontiac Safari uses a 562 bulb for the dome light, while the 1989 model year uses a 561 bulb.
Both the 561 and 562 are festoon-type bulbs, meaning they are cylindrical in shape and make electrical contact through metal caps at each end rather than through a base socket.
A festoon bulb is held in place by spring clips that press against its end caps, a mounting method common in interior dome light housings.
Both bulbs share identical physical and electrical ratings: 44mm in length, 12 volts, and 12 watts, making them dimensionally and electrically equivalent to one another.
Despite their shared specifications, the 561 and 562 carry distinct ANSI part numbers, and fitment data for the Pontiac Safari assigns each to specific model years rather than treating them as interchangeable.
Both bulbs conform to ANSI standards recognized in the United States and Canada, indicating they meet a defined set of performance and construction criteria for the North American market.
At 12 watts, these bulbs fall within the typical low-wattage range for automotive interior lighting, where heat output and current draw are kept minimal.
