1971-73 Ford Mustang LED Bulb Application Tables

In the following charts the wild card character "X" is used in the suffix in place of the color code when a variety of colors may be selected by the customer to replace a given bulb. For example, if the table shows a result of BA9S-SMD-X, then any color BA9S-SMD bulb can be used in that location, based on the customer's desired appearance. The "X" is only used in the "Also Fits" column. Information provided in the "Best LED Bulb" column is intended to provide results that preserve the factory lighting colors.

* The switch bezel illumination sockets in the 1971-73 Mustangs are wired in reverse from the factory. In order to use LED bulbs in these locations, You must install a non-polarized bulb or the positive and negative circuits on these bulb sockets must be rewired to correct the polarity of the socket.
t Colors other than FC, BL, & GN may require the removal of a factory installed color filter lens. Some lens filters may not be able to be removed or may require significant disassembly to remove. Please determine the level of disassembly required before ordering LED bulbs in yellow or red.

 

In the table above, the wild card "Z" is used in the suffix in place of the bulb color. Use the table below to determine the correct bulb to match the HiPo Parts LED Gauge light kit used in your vehicle. For example, if the chart above shows a BA9S-SMD-Z and you have a HiPo Parts Factory Color (FC) LED Gauge Light Kit for your vehicle, then the correct LED bulb part number is BA9S-SMD-WM. If the kit you have is a "GN" (green) LED kit, then using the table below, the correct matching LED bulb part number would be BA9S-SMD-G.
