Just started installing the new guages. The only reason I went with new ones is because most of the old ones were mechanical and electric are easier to use with an LS2.
Anyways, I expected the guages to be the typical perimiter lighting deal. I was very happy to see they are "glow through" design like a modern car. Very easy to read.
I was also impressed with their LED system. All you do is remove the bulb and plug in a small circut board with 2 or 4 LEDs on it. Pretty slick idea. You use a board with 4 LEDs for a large guage and one with 2 LEDs for a smaller guage so the lighting is consistent. I got red but they come in many colors.
Anyways, just thought I would share..
