1964-1966 Ford Mustang LED Tail Light Inserts. Here is a your chance to update your tail lights with the new LED technology. It just couldn't get any easier! Remove your old lens and bulb, insert the socket and put the screws back in. These tail lights have 68 super bright red LEDs. They use epoxy coated, fully sealed electronics on solid state circuit boards. All the LEDs light up for tail lights and all get brighter for turn signal. These appear stock until you look close. The LEDs are instant on and off. Almost unnatural! They are so fast NHRA had to re-calculate the Christmas Tree when they converted. Low current so they run cool. Tremendous life span. They measure about 5 1/4" tall x 7" wide. We also stock the matching Park LEDs. The listing is for a pair as shown. You will need the LED flasher for these.
