Additional Notes

The 562 and 561 are both ANSI-standardized bulb types recognized across the US and Canadian markets.
Both bulb types follow the festoon form factor, which is a cylindrical shape held in place by spring-loaded end-cap contacts rather than a bayonet or wedge base.
The 562 and 561 share identical physical and electrical ratings: 44mm in length, 12 volts, and 12 watts.
Despite their near-identical specifications, the 562 and 561 are listed as distinct part numbers and are not confirmed as interchangeable within these specifications.
The Cadillac Cimarron uses the 562 bulb for the dome light in the 1984 and 1986 model years.
The 1982 Cadillac Cimarron dome light takes the 561 bulb, which differs in designation from the 562 used in later listed model years.
