2000 Chevrolet Blazer - Fog Light

Replacement Fog Light Bulbs

Fog lights are specialized auxiliary lights mounted below the headlights on the front of a vehicle. These lights are specifically designed to enhance visibility in foggy or adverse weather conditions by cutting through the fog and providing a wide, low-reaching beam of light. When the fog lights are dim, flickering, or not turning on, the first things to check are the fog light bulbs. If the bulbs don't appear to be burnt out, then there may be an electrical wiring or connector issue. The fog light switch, socket, relay, and fuse should be the next items that you test if the bulb itself doesn't seem to be the issue. In some cases, fog lights can also be added as an aftermarket accessory, and these fog lights may require a specific bulb that isn't specified in your service or car owner's manual. When replacing a fog light bulb, it's essential to consult the vehicle's owners manual to ensure the correct bulb type and size for proper fitment and compatibility with the fog light housing.
