1. Park your vehicle in a safe location and turn off the engine. Engage the parking brake.
2. Locate the headlight assembly that contains the burnt-out light bulb. The 2002 Suburban has separate headlight assemblies for the low beam and high beam lights.
3. Open the hood of your vehicle and locate the headlight bulb. The bulb is located behind a rubber cover on the back of the headlight assembly.
4. Remove the rubber cover by gently pulling or twisting it off. Be careful not to drop the cover into the engine bay.
5. Remove the old light bulb by turning it counterclockwise and pulling it out of the socket.
6. Insert the new light bulb into the socket and turn it clockwise until it is snug.
7. Replace the rubber cover and close the hood of your vehicle.
Note: If you are replacing a high beam bulb, you may need to remove the air filter housing to access the headlight assembly.
