Video Description

This video demonstrates how to change a burnt out taillight bulb on your 2003 Chevrolet Trailblazer. Tail lights are also called rear position lights or running lights. Some of the other bulbs in the tail light cluster such as the brake light or turn signal may also function as the tail light in your Trailblazer. It is possible for the turn signal or brake light to work but the tailight part to be burnt out - replacing the bulb on your Trailblazer will restore functionality to both. Since the tailights are on whenever your parking lights or headlights are on, they will burn out eventually. Burn out tail lights are a common reason for a police officer to pull you over, so we recommend changing all of the tail lights on your Trailblazer whenever one is burnt out.

When changing the tailight bulb on your Trailblazer, be careful not to touch the glass part of the new bulb as this will cause the tailight bulb to burn out quicker.
