Fit In Five Steps

How to replace a Chevrolet Silverado GMC Sierra 1500/2500/3500 Smoke Lens LED Third Brake Light?

1.Materials Needed for Repair

• ¼ extension – 3-inch and 6-inch
• ¼ ratchet
• ¼ socket set – metric
• Dielectric grease
• Replacement bulbs
• Screwdriver – Phillips
• Screwdriver – slotted
• Torx driver – T10, T15, or T20

Some manufacturers have made it easier to replace bulbs in cars and SUV by allowing access to the inside of the vehicle. If your vehicle has this type you can skip steps 2 through 4. If you have easy access, you may need to easily open the flap or panel over the inside of the brake light lens. By accessing the inside of the brake light lens you will see the brake light bulb socket.

2.Locate & Remove Mounting Bolts

When locating the mounting bolts on your lens assembly, many are obvious but some are covered by cosmetic covers that easily pop off. Once you have found the mounting bolts, remove and set the bolts aside.

3.Remove the Tail Light Lens & Brake Light

Most tail light assemblies come right off. If it gives some resistance, pay attention to the direction the tail light lens is installed and pull straight out. Once the tail light assembly is removed, locate the brake light bulb socket. If you are unsure which socket is for the brake light, either have somebody depress the brake pedal or turn on your hazards. The bulb socket has a release tab; turn counterclockwise to remove. To remove the brake light bulb make sure the lights are off and the bulb is cool to the touch. Pull the brake light bulb out of the socket.

4.Install New Brake Light

After the brake light bulb is removed, take a look at the numbers on the bulb and match them to the new bulb. Apply dielectric grease to the brake light bulb socket. A pea-sized amount is enough to apply to the socket. Take the new bulb and install it into the brake light socket. Mount the brake light socket, match the tabs on the socket and the tail light lens, and, once inserted, turn clockwise to lock.

5.Reinstall Removal Parts & Check For Light

Before mounting the brake light lens, test the brake light function. Line up the tail light and slide into position; line up the mounting holes, and start the mounting bolts. Mounting bolts are tightened hand tight.
