Parking Light Replacement on a 1991 GMC C3500 Sierra 6.2L V8 Diesel Standard Cab Pickup

This how-to video shows you how to change the parking light bulb in your 1991 GMC C3500. The parking lights on a car are also known as position lights or clearance lights. The parking light symbol in the 1991 GMC C3500 dashboard is represented by two small semi-circles facing opposite directions. The parking light is typically orange in color and the parking light bulb may be the same bulb as the turn signal bulb in some C3500s. It is possible for the turn signal filament of the dual function parking light and turn signal bulb to burn out and for the parking light to continue to function properly. Replacing the parking light bulb will restore functionality of both your turn signal and parking light in your C3500.

When changing the parking light in your C3500, be careful not to touch the glass part of the new bulb with your finger as this will cause it to burn out quicker. We recommend using gloves or a piece of paper towel to limit the potential of touching the bulb.
