If you do a light coat of white on the back of the gauge face (too much will darken your light altogether) it will help. If the bulbs you're getting have the one on top pointing directly up, the best thing to do is to soften this one a little, as these are the ones that give you the real hotspots because they're pointing straight at the gauge face. There really isn't a good easy way to do this, but most of them have part of the clear plast that protrudes out toward them. Adding some tint to this might help, but it also may make your needles dimmer. I've actually had a bit of luck using the single LED bulbs (big clear plastic dome) and reshaping them with sand paper, making them beveled, and flattening the top, then putting a drop of paint on top. The thing about these is that they don't give off as much light overall as the multiple LED ones, particularly the ones full of SMDs. Assuming you are working on a spare cluster, I would just do a little experimenting until you get the desired results.
