just remove needles, clear the paint off the back of them with isopropyl alcohol, then clear the paint off the back of the gauge face with acetone and qtips carefully. dont spill any on the front. this will make everything see-through. then you can get some white glass paint and paint the bottom of the needles so you can see them. then all you do is wire in some blue leds and youre good. you can glue them to the bottom of the clear plastic shield.

well its just a power and ground wire, you can tap it to dash light power that dims and then they will work with the dimmer. it just depends which wire you pick.when i did the dash leds, i wired them to work with the dimmer so its like stock.
where can i get the new blue bulbs, are they a certain size or somthing?
where can i find all this isopropyl alcohol,acetone, and white glass paint. Ace Hardware?

alcohol from walmart 90% proof, acetone hardware paint dept, glass paint from michaels crafts. these are not bulbs, they are LEDs, and you can find packs of em on ebay. id say get a 100 pack in case you mess up. i used about 40. and i wired around 4 of em in series and then sets in parallel. theres a led hookup faq in the lighting forum with daigrams.
I just did my Climate control in Red, and I'm about to do the cluster also. I took off the orange so now it's just white, but I got tired of it.
So groups of four in series? I was thinking maybe three in series to get it back down to a reasonable brightness, but I'll defer to your judgement. If you're not gonna do a DIY pictorial, I'll be happy to write one up when I do mine.

well it all depends on the leds. you can wire only so many in series until the total forward voltage exceeds the total input voltage from the alternator. so if you do red its around 2v and when you hook 7 together its around 14v then you need a bit more resistance. its always better to slightly underpower them and resist for 15v so they last a long time. it all depends on the leds color used. if you are just doing red, you can keep the stock bulbs and put red taillight repair tape behind the gauge face once its cleared. comes out great and you can put lil squares of paper on the hot spots to even out the lighting. but here is a very rough way to wire the leds. like i said it will vary and you will have to figure out which resistors to use.

actually this is the very first dash and cluster change i made, the cluster backlight was actually EL wire to match the cd player. its completely different now but ive always liked blue

and a few led hookup diagrams i made

Why would you want to? It's much more satisfying to make your own.
GB- so, if I were to use red LEDs, I would have an individual voltage of 2V each. Cause right now, I have each individual bulb with a resistor that's, I think, 6.2 ohms. Does that sound right? But If I were to wire up an array of seven LEDs in series, what strength resistor would I need, or how many? Or would I need one at all? Because the total voltage would be in the ballpark of 14V.
Sorry for the questions, I just wanna make sure I do this right. I can't remember all this stuff from Physics. Must have slept through that day.

you just use this and turn off your brain lol. but you need to know the info from the led manufacturer you bought from. forward voltage is typical 2-4V but its always different depending. red is around 1.9v and blue/white is around 4 but thats guessing. the led current is usually 20mA but it also varies. the total voltage i would say go 15v cause sometimes the alternator makes more than 14.4v and you dont wanna burn the led out early.
