Ford Maverick Parking Brake Indicator Bulb Size

Additional Notes

• The Ford Maverick uses the 194 bulb for the parking brake indicator across all listed model years, spanning 1970-1977.
• The 194 is an ANSI-standardized bulb type, meaning its specifications are governed by a recognized North American standard applicable in both the US and Canada.
• This bulb follows the T10 miniature wedge form factor, a base style that relies on two angled plastic legs to friction-fit into a socket rather than using a metal bayonet or screw base.
• The 194 operates at 12 volts, which is consistent with the standard electrical system voltage found in conventional passenger vehicles of this era.
• At 3.78 watts, the 194 draws a relatively low amount of power, which is typical for instrument panel indicator applications where continuous illumination is expected during a warning condition.
• Because the T10 wedge base is a widely produced form factor, multiple manufacturers produce 194-compatible bulbs, though fitment depends on the socket housing accepting the wedge base correctly.
• Substituting a bulb with a different wattage rating in a wedge socket of this type can affect socket temperature and indicator brightness, even when the physical base is compatible.
