Ive looked everywhere on how to change the back light on the 5th gen cluster to LEDs and cant find a tutorial which i saw months ago... it was an amazing how to with everything that had to be done and what Leds to buy so that you could still adjust the brightness.. if anyone has a link or knows what to do could they please post it up??

thanks, i would really like to do this but dont want to spend ages figuring out what LEDs to buy when the cluster is out as i need to use my car fairly often..

thanks
Ben

check out superbrightleds.com

I have converted mine to l.e.d.s and it looks great. It is quite easy to do as well, and you can still use the dimmer switch with them as well.

would you be kind enough to write a list of the LEDs needed to swap only the cluster to Leds?

I know the bulbs you will need are 194s.

I cant remember the exact number you will need, but are you planning on converting anything else? like the dome light and what not?

I would suggest getting ten bulbs, just to be safe. I know that you wont need ten for the gauges, but in case you decide you want to do anything else.

i got the 6 l.e.d. bulbs for mine.

What color are you going to do them?

I checked the back of a spare cluster I have, and there's 5 tinted lights, the other 194 is for the low fuel light.

Ahh, Ic.. well there you go.. You can also change the color of the key ring, the ash tray light, and rear hatch light and dome light.

there was a better write up somewhere that showed you how to even pull the dash apart and gave part number's from superbrightleds.com

I just snuck my gauge cluster out very carefully so I didnt have to disconnect the climate control cable.. It wasnt too hard...

http://superbrightleds.com/mini-wedge.html

You will need 194's(i would get a couple extra just in case)

If you are wanting to do the ash tray or key ring, you will need some #74's..

I know if you get jdm corners, you can use 194's in there as well.

For the dome light you will need the 3022's(i am pretty sure on these, you can also use these in the rear hatch light(the smaller 4 led ones) and in the door lights as well, but in the dome light i would use the larger brick one).

yeah thats the thread i was talking about, really helpful..


so 194s, cheers, i plan on just changing the back light of the cluster to green...

Went to the local electronics shops, bought 18 blue leds, putted them in 6 x3 (serial) into the stock sockets.
no resistors, and you can dimm them (as normal). key ring also done, 1 extra LED + 8.3V zener.
You want to buy wide angle leds else you need to adjust them a bit (which i needed to do).

now i want to change the heather buttons aswel to blue, but in the tutorial mentioned above is said not to remove the entire front dash panel. because on the right it cant be removed or so... but thats were i need to be... right side lights... how to get it off?

See the thread I linked.

djorkaef
01-25-2009, 03:55 PM
yes that thread just says 'remove the panel'. the other, turorial thread says


And after that's done you'll be able to pop out the left side of HVAC control shroud. After you pop out the left side, the right side only pops out but can't be pulled... so don't try.

So i dont know what to do... pull and pull until it breaks or what...

If you don't have automatic climate control, there are two cables that connect to two butterfly valves, one blue one that runs outside the car into the engine bay, and one red one that runs down near the driver's side kick panel on the center console. If you get down on your back, you'll be able to see the cable, it's mainly held in place by a snap fastener. I've seen pictures of them somewhere. The easier one is in the engine bay.

If you have a friend to help you, it'll make identifying it easier, because they can push and pull gently on the HVAC controls which will make the cord wiggle.

Sorry I don't have any clear pictures to help out.

that sounds like a hard job just to change one or two lights... :s without pics i can't do it i think. don't understand the whole ting... DO you know there are lights that can be changed after there?

djorkaef
01-25-2009, 05:19 PM
I found the blue wire and its lose. But no sign of the red one... i getted on my back were the pedals are but i cant see anything move when pulling the panel. that pics would be very welcom, ill search some on internet.

that looks great, I cant wait to do mine, but may be a while. Just to clear something up, one of the write ups says LED's arent normally able to dim, this is false, the reason for the built in resister is to control the amount of voltage the LED's recieve because they require very little. As long as you have enough voltage to light them, they will light, even if its not as bright as it could be

could it be a black cable, like in this thread

Ah yeah, black, that's what it was, not sure why I thought it was red. Glad you found it!

yeah i getted it all out (thank you very much!), electronics until the lamps of the heating panel, but they were so small and 12V so I had to put in 1 zener + LED or 3 LEDS serial and that was really impossible. maybe if i find smaller blue leds later, it could work, or lamps with blue plastics over it in stead of green. where to find is another question...

anyway i putted the whole thing back together and when i tested it it looked good, but suddenly one of the lamps stopped burning so know i only have 3 of 5 heating buttons lighted :(. so i will have to do it all over again (if i find good lamps first).


another thing: the green/oranje fuel economy light could become very anoying if you have this dark blue lighting. the colors just don't really fit together. and that arent just easy to replace leds you must open up the dash panel itself i guess (hope).

if anybody has some tips or hints to find good lamps or leds that fit in (anywere in the dash) let me know please.

who has pictures of their clusters after the color change with led's?
im trying to figure out what color i want to do. i liked the white but also liked the blue. i have seen a red one somewhere and wasnt too fond of it.

im thinking white or blue.

either are bad ass

it's not an easy job but i also changed the other lights in blue and white.

think the hvac blue leds must me stronger and the white leds less.

so i'll have to open it all again and change the resistors : P

djorkaef, I love your setup but, I don't understand this. Somebody mind explaining the whole thing about resistors and such? What, exactly, is needed to change everything (key ring, etc) to blue and have uniform brightness? Thanks-

Sorry haven't been here for a long time. Maybe so,eone can use this information:

The car is sold ant I can not say anymore what resistor values I putted in there. You just need to be somewhat creative and spent time in figuring out what the best resistor values are. This is not a 1-day plug-n-play job. You need to have some soldering equipment, connectors and a 12V power supply to get forward.

The thing is that the original bulbs work on 12 Volt and LEDs use up to 4 Volt. That means you will need to put them in series of 3 in the cluster panel. You can not do this in the side panels and buttons because that will give too much illumination. There you can use 50mA as a current, that means a serial resistor of 8V/0.05 = 160 Ohm. But again you will need to experiment with this value until you are satisfied. Don't forget you can always use the illumination dimmer if you think the light is to strong, but it will effect the cluster lighting too.

Spreading the light is also not easy because LEDs mostly have a narrower angle. You can put blue caps over them or polish them. In the side panel you may need to glue some aluminium foill to spread the light correct.

The white LEDs need to be of a smaller size than regular LEDs because else they will not fit in the switches. The blue LEDs in the door panel need to have big resistors else they will burn to hard (10000 Ohm).

Only do this when it is some kind of hobby and you want to have your own customized interior.

This is a video I made during the job but it is very fastened up and has parts removed:
