Hey All, I'm new here and have been searching around about a light issue with my 08 Trailblazer. I have a minor lighting issue, I searched and found a multitude of models/years that have lights dimming. My issue is the opposite. When I go from a complete stop or even rolling real slow, my headlights and dash lights flicker brighter twice, then go back to normal. It happens at 15 MPH or less but it's consistent, every time from a stop sign, red light, making a turn, whatever. I called the dealer because it is a certified pre-owned and they seem to have never heard of this. Any ideas? Thanks in advance for any and all help!

I’m sorry you are experiencing this issue with your vehicle. This may be due to an electrical issue, possibly a connection issue. This is just a suggestion, not a diagnosis.

I recommend consulting with a certified technician for an official diagnosis. They will be able to offer more information after inspecting the vehicle.

Please keep us posted.
