I have NR Auto el glo gauges. They look slick, but can be annoying driving on a dark road at night. If your mostly in City or other lighted roads at night don't worry about it. That is where I do most of my driving so I'm ok with this. I will say my gauges have been a bit of a pain at times. They are fussy and have gone out before.
Network guy (not sure if that is or or 2 words for his user name) made a very good install page for these. There is a link to it in the garage, but I'm pretty sure there is a link to his page somewhere around here that is not in the garage. Try a search. I think it website was
www.digitalpimp.org or .com or .net or something. That should give you a start.
