How to adjust the headlights and fog lights on Chevrolet Trailblazer?

These models are equipped with composite headlights with adjustment screws for up-and-down movement, but left-and-right movement is not adjustable. To adjust the headlights, a blank wall 25 feet in front of the vehicle and a level floor are needed. Position masking tape on the wall in reference to the vehicle centerline and the centerlines of both headlights. Measure the height of the headlight reference marks from the ground and position a horizontal tape line on the wall at the same height. The adjustment should be made with the vehicle sitting level, the gas tank half-full, and no unusually heavy load in the vehicle. Turn on the low beams and use the adjusting screw to position the high intensity zone two inches below the horizontal line. For fog lights, some models have optional fog lights that can be aimed like headlights. There are no left-and-right adjustments for fog lights. Position tape on a wall 25 feet in front of the vehicle and tape a horizontal line representing the height of the fog lamp centers, as well as another line four inches below that. Use the adjusting screws on the fog lamps to adjust the pattern on the wall so that the top of the fog lamp beam meets the lower line.

Chevrolet Trailblazer Fog Light

The Fog Light system in Chevrolet Trailblazer automobiles is used as a specialty lighting that mainly provides additional illumination for the ugly roads in conditions that are typical for fogs, heavy rainfalls or storms of the dust. Fog lights produce a low intensity beam which is in the form of a bar which reduces the glare on the road surface and making it easier for drivers to see the road surface. Front fog lamps are usually not fitted as standard and might not even be employed in all models and are exclusively for use in low light conditions. Aside from the front fog lights, there're some models of Trailblazer with rear fog lamps- license plate lamps that are bright red and mandatory in some parts of the world to enhance the car's visibility from behind. These rear lights can be installed single or in pairs, legal rules state that they should not be placed near the brake lights. The changes in automotive lighting technology nature have affected the use of fogs in newer models with some going for the DRLs and LED.

Each OEM Chevrolet Trailblazer Fog Light we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
