03 blazer Instrument cluster
 

I'm looking at possibly replacing the whole cluster. First off i have a bulb that's out and was thinking or replacong them with blue LEDs... If this is possible what size bulbs do i need and where can i find these... Also i would like to replace all the guages with white faces.. Once again after an exhausting search I've found nothing to fit my blazer... Any ideas would be helpful...

I think the s10 extreme models had the white backing, can't remember exactly. And if you do a search on here for the cluster exchange, there's a write up. Can't remember exactly by whom, but I know of at least 2 different people who I'd this. Good luck, post pics when your done if you don't mind, wouldn't mind seeing the blue behind the white... seen many black on blue.

Check out this build thread. Tajohns34 gets into detail with different Blue LEDs, and a color changing gauge face.

Otherwise, you can order generic white faced gauge plates like the following:

Ebay might have cheaper, and different styled ones.

Update
 

I just replaced the bulbs with some blue leds... They don't work at all... I just got in another set and haven't installed them yet... I tested the original bulbs that work but when I put the meter to the led's they don't register... I was wondering if there is a way to test them to see if the work...

You might have to flip the LEDs around to get them to work.
Also, when you put them in your cluster, you might have to only twist them 75 percent of the way. Make sure the metal tabs on the twist base are touching the metal strips on the cluster.

I have tried flipping them and still nothing... There are 6 that go in the cluster so the odds of them all being backwards are small... But nonetheless I turned 3 of them 180... I'd be done sooner but my battery died and since i can't legally drive it I haven't been able to get it charged... I'm about to take it to autozone to charge it... Upon further inspection it looks like the contacts go too far... I adjusted 2 of them and will check when I jump the blazer...

Yay...
 

I got them to work... Well one of them... I didn't turn it as far and it works... https://cimg4.ibsrv.net/gimg/blazerf...ad007370a7.jpg

Saweet!

I like the blue, but the red matched better in mine.

What brand red LEDs did you use? I tried to do the same in my old 1998 Mustang, but none of the four different brands of LED bulbs I used were ever as bright as in your picture.

The green LEDs look sick!

Cimmerian, I am not 100% on brand. I ordered them off of ebay, I think. I will look up and post the link later today.

Thanks, I appreciate that.

It was something very similar to these...

Thanks. I'll give those a try when I get paid next if I can find 'em in red.

I like the red... My blazer is red but I want to do the interior in blue... I want to replace all lights with blue on the interior and get the blue halo projection headlights... My next project is taking out the light that shines on the passenger floor boards and putting blue light strips around the bottom on both sides... I was wondering if i could just cut out the socket and use the wires to power the light strips and if so what kind of light strips i need...

Done

This is what it looks like now... I'm going to post another pic when it's dark out... Maybe tomorrow night I'm not sure... Now i need to find a good white overlay and fix the fuel gauge... Sometimes it reads most times it looks like that... I have about 1/2 a tank in it...

Dark outside
 

Looks purple. Love it!

It's just hooked up and not bolted on and the dash is still removed... Plus the sun was out and reflecting trees and stuff... Probably would look too purple when put back together...

It's because you're using blue light on red numbers. Blue plus red equals purple. Would probably look more blue with white face gauges though.

I'm going to do this next... I'm going to take out the light under the passenger side and have 1 bar under the dash on each side and one bar each shinning on the back floor boards... I'm a little hesitant attaching them to the back of the front seats... My wife might drive sometime and she is 5 foot as i am 6'3"... I'm afraid the constant forward and back of the seat may tear the wires... Any ideas??
