Make sure your vehicle is parked on a flat surface in a well-lit area. Set the emergency brake and release the hood by pulling the lever located at the left end of the driver’s footwell.

  • Check that the headlights and key switch are off.

2- Stand in the front of the car

Move to the front of the vehicle. Open the hood by inserting your hand into the gap between the hood and the grill. Locate the lever assembly and slide it slightly to the left. You should be able to lift the hood all the way up.

3- Locate the headlight assembly that is faulty.

Find the two (2) pins at the top of the headlight assembly. Twist the headlight retaining pins until they are free from the headlight housing.

  • If the pins are difficult to remove due to road grime, a flat-blade screwdriver may be helpful. Insert it between the headlight housing and the pin, and gently twist it to displace the pin.

4- Pull the pins

Pull the headlight retainer pins up and set them aside in a safe place. Be sure to note where the pin came from, as they are not interchangeable.

Tips and recommendations:

When changing a headlight bulb on a Chevrolet Silverado certain details can come up:

  • If the bulb burns out again quickly, check that it hasn’t touched the glass part, and that your housing has maintained a good seal and isn’t letting water in.
  • If both headlights burn out simultaneously, then you should check the headlight switch and wiring. Suspect an electrical fault.

Do I have to change the whole headlight or can I just change the bulb?

Depends on the situation. If the light (that is, the headlight) is not working, it is most likely the bulb that needs to be changed. If that doesn’t work, check that the bulb is on by checking the socket with a multimeter. If it indicates no voltage, then the problem is with the headlight housing unit rather than the bulb.

If you know that the problem is in the bulb of the light bulb, all you have to do is change the headlight bulb on your Chevrolet Silverado and that’s it.
