Additional Notes

The Honda Odyssey uses the 74 bulb for the automatic transmission indicator across the 2005-2013 model years.
The 74 bulb follows the ANSI standard, which is the recognized specification system used in the United States and Canada for miniature automotive bulbs.
This bulb is classified as a T5, which refers to a tubular miniature wedge-base type with a 5/8-inch tube width.
The wedge base design means the bulb is held in place by the socket gripping the glass envelope directly, with no separate metal base or pins.
The 74 bulb operates at 12 volts, which is consistent with standard 12V automotive electrical systems.
At 1.4 watts, the 74 bulb draws very low current, which is typical for instrument panel indicator lighting where heat and power consumption are kept minimal.
Because the 74 is a wedge-base bulb, substitution with a different base type, such as a bayonet or festoon, is not physically compatible with the socket.
