Additional Notes

The Toyota Land Cruiser uses the 158 bulb size for the parking brake indicator across the 1979-1985 model years.
The 158 is an ANSI-standardized bulb, meaning its specifications are governed by a recognized North American industry standard applicable in both the United States and Canada.
The 158 bulb follows the T10 miniature wedge form factor, a base type that relies on two angled plastic legs to secure the bulb directly into a socket without a separate metal base or bayonet pins.
The 158 operates at 12 volts and draws 3 watts, placing it among the lower-output bulbs used in instrument panel indicator applications where minimal brightness is sufficient.
The wedge base design of the 158 means fitment depends on socket compatibility with the T10 wedge format, and substituting a bulb with a different base type would not be physically interchangeable even if voltage and wattage ratings were similar.
