alright this is a how to for changing your gauge cluster to glow blue at night. i have tookin this off of another dakota site. you can do another color like red but it just did the blue on this one. if you would like to do the red just reply and i'll tell you what to do
1. The bulbs:

They look a little fuzzy, but they're 5-LED Wide Angle 194 LEDs. They can be pruchased below for the different prices listed:

(scroll down about 3/4 and look for "WLED-x5 LED Wedge Base Bulbs")
Red - $2.79
Green - $4.04
Blue - $4.14
White - $4.29
2. The bases:
In order to use these LEDs on the gauges, you MUST buy new bases for them to go in the gauges. They are 1/2" instrument cluster gauge bases, which can be found at any local auto store which would have this type of stuff. I got mine at Autozone, because it was 9:00 at night, and didn't know where else I could get them quickly. Bad thing is, they cost a whopping $3 each.
3. Now before you track down these parts, you need to know how many to get. If you want to do JUST the gauges, get 5 of each. If you also want the turnsignal lights to be the same color, get 7 of them. I did the turnsignals also, so they would flash bright blue in the daytime instead of standard green. In the end you should end up with either 5 or 7 of these:
4. The rest should be fairly easy. It's just putting them in. Start by removing the dash. If you don't know how to do this, I honestly suggest you to stop, and let someone else do it, because it's the easiest thing do remove in your truck, besides your seatbelt when it's buckled.
5. Remove the gauge cluster. There are 4 screws that hold it in. Once they're out, just pull it away from the dash.
6. On the backside you'll see the stock bulbs. You may need to get a set of pliers to twist them. It really doesn't matter if you break them or not, since you won't be using them anymore. The top two in the center are the turnsignals, the rest are for the gauge lights.
The stock bulbs you will remove look like this:
7. After that, put everything back in. It was that simple. Now your gauges should have went from this:
To this!
