Bulbs in car headlights grow dimmer by at least 21% over time. It is for this reason that they eventually burn out. Sometimes, only one out of the two headlights burns out. During replacement, it is important to replace both the headlights so as to make sure that your truck headlights have the same intensity. Changing both lights will also make sure that the new headlight does not appear brighter than the other one.
Precautions to Take When Changing Headlights
Make sure that you use certified Chevy Silverado parts when replacing the bulbs. This will make sure that you avoid compromising pre-engineered system performances, manufacturer’s warranty, and reliability of your car. It is also against federal law to use non-complying parts in servicing. Look into the Chevrolet website or visit a certified dealer to make sure your new headlights are certified and are the best match for your vehicle model.
- If the bulb is a halogen bulb, be careful not to scratch or drop it. This may result in an explosion. Broken pieces of glass also pose potential injuries.
- Make sure you turn off the lamp before replacing the bulb. This will allow the bulb to cool down so that it does not burn you when you touch it.
- When changing headlights, it is recommended not to touch the glass part of the bulb with your bare hands. Oil from fingertips will make the touched part of the bulb hotter than the rest of the bulb. This will shorten its life span.
Steps in Changing the Headlights
Make sure you have a 10mm socket, pliers, and a flatbed screwdriver before you start.
1. Removing the old bulb
2. Make sure that your car is parked on a level ground making sure that all tires are inflated to full pressure. The area where you will be servicing your car should be clean and well lit.
3. Set your emergency brake on. For safety purposes, make sure that both the headlights and the key are off.
4. Pull the handle with the “open hood” symbol on it. The handle is located on the left side of the brake pedal inside the vehicle.
5. Locate the secondary hood release by inserting your hand in the gap between the center of the grill and the hood. Push the secondary hood release to the right and lift the hood.
6. Use a flathead screwdriver to remove retaining clips that secure the radiator cover to your car. Insert the edge of the screwdriver into the middle of the clip and tilt the screwdriver downwards. Do the same for the remaining seven clips. Set aside the panel after removing the clips.
7. Remove the four 10mm bolts that are found right under the shroud cover.
8. Use a pair of pliers to remove the four clips behind the grill. Push the clips together and then pull the grill free after making sure that all four clips are free.
9. Remove the two 10mm bolts behind the headlights.
10. Pull the center panel located on the wheel well. Locate the 10 mm bolt securing the headlight.
11. With all three bolts out, slowly pull and twist the headlight out. As you pull out the light, make sure you detach the headlight from the wiring harness by squeezing the top of the connector. Pull gently so as not to damage the harness.
12. Remove the bulbs by turning them counterclockwise and slowly pulling out. Disconnect and safely dispose of the old bulb.
