So, I installed my Prosport gauges yesterday and my verdict...I like them a lot. I have an electronic boost gauge and EGT gauge, *so these gauges perform the self test sweep. Here's some pics during the day. The face is only slightly visible under bright sunlight, which would be while my windows open.

1)Here's one with everything off. You can sort of see the face on the left gauge, but not the one on the right.
2)The second pic is of the old ones (AC Autotechnic S7 Invision)

1)This is the white light with just the ignition on ACC, it's the same with the car on too.
2)The second one is the old again and notice how much dimmer they are compared to the Prosports?

This is what the lighting looks like with the parking lights on. It's still fairly bright out btw. My old ones stayed one color so there's really no comparison here.

This was all during the day at around 4pm, so there was still a lot of sunlight and IMO, they are plenty bright during the day, which was one of my concerns because of how hard my old ones were to see at the same time.
I'll get some night pics in a little bit too.
*edit, sorry, but the night shots turned out too dark. There's no background lighting to judge for brightness. Anyway, the gauges are brighter than my dash lights and they are pretty bright too.

Those are sick. Where did you get those

I got them from Prosportgauges.com (http://prosportgauges.com/Performance%20Gauges-Amber.htm)
They are inexpensive for their quality. A manual boost gauge is around $37. I bought an electronic boost gauge and EGT gauge, I got an electronic boost gauge so that it will match the EGT when it does it's self test and sweeps the needle.
