Yeah, that's what Cuzoe mentioned to me that kicked off this whole possible solution idea. I'm not confident adding an 'Instrument Lightning' slider will solve my issue, as all 3 that I've tried, Footwell, Front Ambient, & Door Ambient, all just change the color of the needles on the digital dash when I slide them.

But, I figure it's worth a shot. I think my better chance at a solution is finding how to reduce the max brightness, as it
has to be in there somewhere.
