Additional Notes

The T5 miniature wedge is the sole bulb type listed for the Honda Accord automatic transmission indicator across all model years in these specifications. It operates at 12 volts and draws 1.4 watts, placing it among the lower-wattage bulbs used in automotive instrument panel applications.
The T5 designation refers to a tubular bulb with a width of 5/8 inch, and the wedge base style means the bulb is held in place by the socket walls rather than by a separate bayonet or screw mechanism.
Bulb number 74 follows the ANSI standardization system, which applies to both the United States and Canada, meaning the same part number is valid across both markets for these vehicles.
The 1.4-watt power draw of the 74 bulb is consistent with indicator and warning lamp applications, where low heat output and long service life are prioritized over brightness.
The Honda Accord used the 74 bulb for the automatic transmission indicator across the 1982-1985 model years and again in 1990-1991, with no variation in bulb specification across those years.
Because the wedge base relies on socket tension for retention, substituting a bulb with a different base type would result in an incompatible fitment, even if the voltage and wattage ratings were otherwise similar.
