Additional Notes

The Isuzu Hombre uses the 561 bulb size for the dome light across all listed model years, spanning 1996-2000.
The 561 is a festoon-type bulb, meaning it is cylindrical in shape and makes electrical contact through metal caps at each end rather than through a base socket.
The 561 bulb has a length of 44mm, which is the critical fitment factor for festoon bulbs, as the housing retains the bulb by tension against its end caps.
The 561 operates at 12 volts and 12 watts, which is standard for automotive interior lighting applications.
The 561 designation follows the ANSI standard recognized in both the United States and Canada, meaning bulbs carrying this designation from different manufacturers share the same electrical and physical specifications.
Because festoon bulbs are retained by spring-loaded clips rather than a twist or plug-in socket, substituting a bulb of a different length risks either a loose fit or an inability to seat properly in the Hombre's dome light housing.
