i'm getting another digi to mess with to try this out to see if its feasible, and i can see mine fine in all times of day, maybe i can jsut see the green a lil better then other people, but if the color was changed to something wiht higher contrast that wouldn't be a problem anymore
edit: ok so if you guys havn't figured it out yet, i might be able to get custom digi gauges for the 300zx's, if i can get enough people that are interested, we would be the ONLY Z owners with these(seriously this is a one time offer), which personaly i think would be awesome, our cars would be that much more unique and exotic, i don't know prices yet and proly wont unless i can get enough people that are interested, so if have ever wanted your digi gauges to be a different color, let me know, and lets see what colors you would have for each display (i.e speedo, fuel, tach, etc.)
