Surely....
This is a pic of my cluster during the day: (sorry most of these images I had to use still captures from my camcorder...gotta re-borrow my dad's digicam sometime and get some new shots)
taken at about 5pm in the afternoon...shows just how bright the cluster is (of course you can dim them according to your preference with the stock dimmer switch)
unlighted cluster in the afternoon
cluster at night...sorry my digicam has crappy focus, but this shot shows the difference in colors, since I put little transparent sticky tabs behind each individual hash mark to make them green like my exterior color (you can choose any color you want)
how it looks outside the car
I used to have white, 5 color indiglos but changed it out because I like the stock look at day, and the lighting really shines up the cabin and gives it that subtle aftermarket look at night.
Wish I could do dark L.E.D. blue, but I think that's pretty much impossible with our 4th gens without losing tons of output because the back of each gauge face actually has transparent turquoise built in.
As for the bulbs, I just replaced all the stock 194 mini wedge bulbs (3 of them) with 3 large wedge bulbs (model 7440), usually used in backup or signal lamps.
You could go with hyper white or red or blue or whatever, but I just went with regular clear cheap 99 cent ones at the local auto store and I'm happy with em. I'd rather go with oem bulbs and not take the risk on crappy second hand manufacturer bulbs and have to keep re-opening the dash.
And the sticky tabs...hermm...I'll have to take a pic of those too...they're just regular little 'sticky' pieces of tape with colored tabs at the end....they're meant to be book page markers, and you can find em at most any book or hobby store or in the school supplies section.
I'll take better pics soon.
