Ok to start with, yes I was sober. Every time I hit a bump it seemed like my stock cluster was getting bright. I got a 09 and run it as dim as it will go. I've been driving a rental 2012 Silverado and before that my beater 99 s-10 blazer. Just hopped in my LMM today and it seems every time I hit a bump my stock gauges have been getting bright. I'm going to check the ground I used for the banks when I took it out. But anyone ever see this? Hope this is the right area for this post.
