Additional Notes

The Honda Prelude uses the size 74 bulb for the automatic transmission indicator across all listed model years, spanning 1979-2001.
The 74 bulb follows ANSI standards as recognized in the United States and Canada.
It is a miniature wedge-type bulb, classified under the T5 designation, which refers to a tubular bulb with a wedge base rather than a traditional bayonet or screw fitting.
The T5 wedge base is self-retaining, meaning the bulb is held in place by the socket walls rather than by a locking mechanism.
The 74 bulb operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles of this era.
At 1.4 watts, the 74 bulb draws very low current, which is typical for instrument panel indicator lighting rather than exterior or high-visibility applications.
The consistent use of a single bulb size across the full 1979-2001 production span of the Honda Prelude indicates a stable fitment requirement for this specific application throughout the model's history.
