Last Updated August 8, 2023 | Bill Tumas

Parking lights for classic Mustangs are an important safety feature that can wear out over time. Switching out your 1965-1966 Mustang parking lights with new LED replacements is not only a great way to give your classic Mustang a modern look, but also an important safety upgrade if your stock bulbs have gone dim.

Check out this guide for step-by-step instructions on how to replace your classic Mustang's parking lights with LED upgrades.

1965-1966 Mustang LED Parking Lights Install Instructions

The LED parking lights we installed are sold as a pair and are a direct replacement for the factory lens and bulb. The installation is super easy, requiring only a flathead and Phillips-head screwdriver. It will only take 20-30 minutes, so you should be back on the road in no time.

Step 1: Remove Factory Lens

Under the front fender is the factory parking light. Using a Phillips-head screwdriver, remove the two screws holding the lens in place. You can discard the old lens, but keep the screws.

Step 3: Install New LED Wiring

On either side of the new LED socket are alignment pins. The higher pin will go at the top of the housing, with the lower one at the bottom.

Slide the socket into the housing and push it forward with a flathead screwdriver. Turn it clockwise to lock in the LED.
