I know from my experience that it needs to be done with the correct amount and color, if there is to much it looks bad, and if it doesnt blend with the interior thats not good either. I have used led's under the dash in my element and under the back seats that really made a huge difference at night. I was looking at the ridgeline and it does need some lighting in the front/rear floor areas. I was wondering what everyones opinion was for a good color to match the olive leather interior. (red,blue etc.)
