Subaru Loyale Map Light Bulb Size

Additional Notes

• The 168 bulb is the specified map light bulb size for the Subaru Loyale across the 1990-1994 model years.
• The 168 bulb follows the ANSI standard, meaning it conforms to a recognized North American specification used in both the United States and Canada.
• It is a miniature wedge-type bulb, classified under the T10 designation, which refers to its tubular form factor measuring 10 millimeters in width at the base.
• 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 involved.
• The 168 operates at 12 volts, which is consistent with the standard electrical system voltage found in conventional passenger vehicles.
• Its rated wattage of 4.9W places it in the low-power category, typical of interior courtesy and reading light applications.
• Because the same bulb number applies uniformly across all five listed model years, the map light socket specification did not vary within this production span for the Loyale.
• The T10 wedge format is shared by several bulb numbers in the miniature automotive range, so substitution with a physically similar bulb of a different wattage rating would not constitute a correct fitment for this application.
