Now I can't take total credit for this, as the idea was not mine.

There used to be an article on this site that I believe was written by Karbonphyber. For whatever reason the article was removed along time ago and hasn't returned. So I thought I would knock something up as quite a few people keep posting up asking how to swap the stock lights for LEDS.

Choosing you LEDS:

LEDS are a semiconductor device, which means they use a semi conductive material (silicone) to operate. This semi conductive junction can only support a specified amount of voltage/current before it breaks down (blows). A cars battery provides between 12 and 14V, a typical LED can support a maxumium of 4V before it blows. that is why a resistor must be used on the annode of each LED. The resistor drops the extra 10 or so volts, so that the LED only gets 4V max.
Connecting LEDS without the resistor will cause them to blow.

The stock globes are 3mm, so 3mm LEDS are an ideal replacement. I have used 3mm Hi-Bright White LEDS from Dick Smith (Dick Smith Code: Z3800). And resistors of 360 ohm were chosen to allow for any voltage spikes up to 14V. You will need to choose appropriate resistors depending on which LEDS you use. If you dont know how to calculate it PM me with the data below and Ill do it.

But if your LEDS have:

FWD Current (MAX) of 20/30mA
FWD Voltage (TYP) of 3.5/3.6V
FWD Voltage (MAX) of 4V

Then you can use 360 ohm resistors. This will provide the LEDS with a 3.6V supply at up to 14V battery voltage. So now you've got the LEDS and resistors its time to get started.

So heres what you do:

STEP 1: Remove the unit (I'm sure you can work that out for yourself)

STEP 2: Locate and remove the globe holders (use a flatblade screw driver and turn anticlockwise)

STEP 3: Remove the stock globes (unwrap the legs from the holder - use a jewellers screwdriver, and pull them out gently)
Attached Image: PB010075.JPGAttached Image: PB010082.JPG

STEP 4: Grab your LEDS and poke them through the holes in the holders
Attached Image: PB010083.JPG

STEP 5: Bend the short leg (cathode) of the LED over and into place (the same as the stock bulbs were) cutting off any excess.
Attached Image: PB010089.JPGAttached Image: PB010092.JPG

STEP 6: Cut one end off a resistor so it is about 10mm long, do the same to the long leg of the LED (annode) .Then solder the resistor onto the annode. (apply some solder to both the LED and the resistor first, so they will solder together quickly.)
Attached Image: PB010095.JPG

STEP 7: Bend the annode of the resistor around on itself (making sure it doesnt touch itself) then bend it around like the stock bulb was. Flatten the wire along the LED side of the holder so that it will sit flat once reinstalled.
Attached Image: PB010096.JPG

STEP 8:Install the holders back into the unit.
Attached Image: PB010099.JPG

STEP 9: Reinstall unit into vehicle (You took it out so you know how to put it back in!!) Just connect it to the wiring for now (dont screw it in) so you can test it works first.

STEP 10: Turn the dash lights on and make sure all the LEDS light up. If some don't take those ones back out (thats why we havent screwed the unit back in yet) turn them 180 degrees and reinstall.

STEP 11: Reinstall unit completely.

- LEDS are polarised, which means they have a +ve (annode) and -ve (cathode) and must be connected in that way, otherwise they dont work. Thats why we turn them round 180 degrees if they arent lighting up (because usually they are just round the wrong way).

- Its important that the resistors dont touch themselves when they fold over, as this will create a short and the resistor will be bypassed, meaning the LEDS will get full power and quickly blow.

- If the vent select icons (bottom left) are too bright, remove that LED and lightly sand the top of it. This will disperse the light out the sides rather than the out top.

It might be an idea to sand the led's with wet/dry to give a matte effect to distribute the light better

Nice guide. :)

I did this months ago, but with blue LEDs to go with my lighting scheme, lol. :rolleyes:

would a 5000mcd led be too bright??

#9 Guest_THE ASHMAN_*

^^ Mine are 1500 Mcd and I wouldnt want to go any brighter than those.

I swapped to the white led the other day... Massive improvement over the blue. Now, where to put those spare blue ones??? Any suggestions?

#11 Guest_THE ASHMAN_*

Posted 30 November 2007 - 10:16 AM

You could try putting them in the switches (hazard, fog light, demister etc) so they light up blue. I assume they would have the same type of setup as the climate control.

Awesome guide, looks so much better than the stock bulbs & only a fraction of the price too!!!

Good write up mate. The only thing I would suggest to do on top of that is either

Option1: Slide some heat shrink over the resistor after step 6 Attached Image: PB010095.JPG

Option 2: after completing step 7, get mum's hot glue gun out and put a dob of glue over the exposed resistor/LED legs Attached Image: PB010096.JPG

This way they will be protected from shorting against itself or anything else it may contact. :)

is their anyway to change the digital backlight part? or to much trouble?

#17 Guest_THE ASHMAN_*

Posted 04 March 2008 - 04:26 PM

You meant the actual screen where it displays the temperature???

If thats what you mean, then no, its all one sealed unit, with vacuum flourescent backlighting.

jsut did mine to bright red. worked a treat. only get jaycar etc to match the resistor to the led you choose to be safe. took me bout 20mins. well worth it

It is now, I had that LED round the wrong way when the pic was taken. (just needed to be turned 180)

think i might do this to mine
as it gets real hard to see at twilight

EDIT: thanks for the wright up btw ASHMAN :thumbsup:

I just bought direct replacement 12v t3 leds from ebay costme like 5 bucks didnt have to do nothing but screw old ones out and put new ones in. They look great aswell lol

cheers for the write up dude i also put one in the rear demistor switch and works sweet too.
if anyone knows how to dismantly the hazard and or fog light switches let me know and ill see if it can be done to these switches. Im currently stuck on opening them.

Finished this mod last night & would like to thank the OP. I put some heatshrink around the resistor & LED anode, folded it down & then heatshrunk that as well. I used 3mm blue 1500mcd LEDs from Jaycar & think they look pretty alright, not too bright at night & a relatively even distribution of light.

Has anyone been able to source or find out what LEDs are used behind the recirculation indicator for example? They're little rectangular-ish ones. I don't dare replace them without knowing what voltage & current they are supplied with. I think if replaced with red ones with a blue backlight, they'd look quite good.

Thanks for a great guide!

Does anyone know if there are 4 LED's for the Analogue version too? I only managed to find and replace the two on the top under a plastic flap so far but havent had time to take a proper look.

I also just bought 4 of the T3 LED type ones off ebay for $10 so theres no soldering required, just direct screw in swap.

i bought some off ebay they didnt seem to work doesnt matter which way i put them and now my old bulbs dont work either...any ideas?

yes i tried both ways.

oh and the ebay ones were bad quality and broke apart when removing anyway.
