The Electro-Luminescent Instrument modification for '65-'73 Mustangs from Mustangs Plus is a groovy restomod trick because it looks great and helps you see the instruments better at night. Pioneered and manufactured by Scott Drake Enterprises, the Electro-Luminescent instrument face is a semiconductor that offers a soft green or blue glow when the parking lights or headlamps are turned on. You can also wire it to light up whenever the ignition is turned on.
We're going to install the Electro-Luminescent kit in a '67 Mustang instrument panel. Some minor modifications are required, which are easy to perform on your home workbench. You can take two approaches with the installation: ditch the factory instrument lamps or keep them. If you keep them, you can see the odometer better and they'll also provide some fill-in light. Keeping them also means you'll have to use a different approach to wiring in the Electro-Luminescent faces.
