Right, the luminous line controls the gauge lighting, not the night panel lighting. I knew that, but stated it wrong. Thanks for clarifying that, Commoner, I kinda wondered about the day & night lines there.
However, luminous=200,200,101 is what Kwiekk set that line at, which does render a light yellow, he said he's still getting a red, so we still don't know what the problem is there.
