1999 GMC Suburban Brake Light Replacement

If your 1999 GMC Suburban’s brake lights aren’t working, you can utilize this guide to replace them. While not as widely known as the Chevrolet version, GMC produced a Suburban from 1937 to 1999.

Brake lights help other cars see that you’re slowing down or stopping. Without properly functioning brake lights, other drivers may have difficulty anticipating your movements, increasing the risk of a car crash, especially at night.

Step 5 requires you to remove the bulb from the socket. The bulbs are made of glass so handle them with care to avoid shattering them. In addition, avoid touching the glass with your hands, as the oil and salts on your fingers can cause a hot spot on the bulb, leading to a reduced lifespan. To prevent this, wear nitrile gloves. The bulbs tend to burn out around the same time, so if one goes out the others will follow soon after. When you replace one bulb, it is a good idea to replace all of them at the same time to avoid repeating the repair multiple times in a short period.

Before you begin, turn off your car, put it in park, and engage the emergency brake.
