I'm split between the original Ultra-Lite and Ultra-Lite II for nitrous and fuel pressure gauges. The original Ultra-Lite series uses an incandescent lighting around the perimeter but can be replaced with LED's of various colors. The face is white in the daytime and black at night. The Perimiter lights, light up the outer edge and markings at night. The Ultra-Lite II uses LED's that show through the background. The face is white in the day and black at night. At night the LED's show through and light the markings white and incremenetal markings amber. The LED's on this one can only be replaced by the factory but I was told they last 100,000+ hours. Please help me choose. I hate ordering something like this site unseen. I got the description from the links below but I can not find pictures of either at night. If you have pictures please post them.



Thanks
