Additional Notes

The 158 bulb is the sole instrument panel bulb type listed for the Honda Motorcycle CB1000, covering the 1994-1995 model years.
The 158 designation follows the ANSI standard used in the United States and Canada, classifying it as a standardized miniature wedge bulb.
The 158 bulb uses a T10 wedge base, a small wedge-style fitting that requires no locking mechanism and is retained by the socket's spring tension alone.
The bulb operates at 12 volts, consistent with the standard electrical system voltage found in most motorcycles of this era.
At 3 watts, the 158 bulb draws a low level of power, which is typical for instrument panel illumination applications where brightness demands are minimal.
The T10 wedge form factor is shared across many automotive and motorcycle instrument clusters, meaning physically compatible substitutes may exist, though electrical ratings must match for correct operation.
