Additional Notes

The Honda Accord instrument panel draws from three distinct bulb sizes across its model years covered in these specifications: the 194, 158, and 74.
All three bulb types are ANSI standardized for the US and Canadian markets, meaning they conform to a shared North American specification rather than a proprietary or regional standard.
The 194 and 158 are both T10 miniature wedge bulbs operating at 12V, differing only in wattage: the 194 draws 3.78W while the 158 draws 3W. Despite sharing the same T10 wedge form factor, these two types are not rated identically and are listed as separate sizes in the specifications.
The 74 is a T5 miniature wedge bulb rated at 12V and 1.4W. The T5 wedge base is physically smaller than the T10, making the 74 incompatible with sockets designed for the 194 or 158.
The 1990-1991 Honda Accord instrument panel uses the 194 bulb, the higher-wattage of the two T10 types present in these specifications.
The 158 bulb appears in the 1976-1978 and 1983 and 1985 Honda Accord instrument panels, representing the most frequently recurring bulb type across the model years listed.
The 74 bulb is specified for the 1982 and 1984 Honda Accord instrument panels. Its T5 base distinguishes it from all other bulb types in these specifications.
