Like the title says, I noticed today when I put my car in reverse, the cluster lights briefly dimmed for maybe a quarter of a second. Not sure what could be causing it. Fresh battery, battery is good, terminals are tight, and no corrosion.

The cluster lights only dim when i put the car in reverse, and only for a brief second like I said, then they go back to normal. I can put the car in reverse, put it back in neutral, reverse, neutral, etc... every time it hits reverse it will dim.

Searching didn't really yield any relevant results, I was curious as to if anyone has had this issue before?
