I got mine with the full option list, so I have the dimmer control and truthfully, sometimes I do run it at lower brightness at night. Definitely Order it so that you have a dimmer control (not sure which of the options gave me that, I have ALL options.)

But the graphics are not an issue at all. At least mine aren't, mine are just standard Crossfire Roadster Graphics with my avatar added. I can see behind me, night or day, just fine.
