View Full Version : you can light up your speedo with LEDS
puzzle man
29-07-2005, 09:42 AM
hi guys i replaced my speedo lights with LEDS didn't see the problem some of you were having with it lighting up specific areas like a spotlight. I used these LEDS that I found they have concave lenses, which helps disribute the light more evenly then the regular ones that are avaliable. This picture shows the bulb near a piece of perspex, from how I see it the light beam hits the perspex and then is re-directed into the area of the speedo. There are 4 LEDS that can be replaced with 3 that are used to light up the speedo area and a 4th one which is used for the battery light. I only replaced the 3 that are used for the speedo. I used red LEDS but you can also find them in yellow, green and blue I purchased mine from Pep's Auto but you can get them from Autobarn aswell. They are rougly around $10-12 for 2 LEDS, they are like a wedge style globe - the same as the ones that go in your indicators. One point to remember if your thinking of doing this is to undo your speedo cable from the engine bay.

While I had everything out I also decided to paint my speedo surround. I used a plastic primer, then several coats of colour and a clear just to give it a glossier, brighter look.

Do you have any pics of these leds?
Do they have the required bases on them or just 2 legs like your normal leds?

no... but i'll take the piss out of your spelling though :P
There are alternative reasons for procurement of this product..... afterall i have already done a conversion like this back in 2002 when ultrabright LEDs first hit the market, and were available in such nice, easy to use plug in packages.... i used hot glue, solder, sandpaper and a transistor dimming circuit.
I was actually going to do this with some Luxeon LEDs with their new "side emitting" lenses in the RA28.... but im a bit lazy after having spent so long doing it before.

I don't know about Witzl but for me it was the following comment:
$10-12 for 2 LEDS
1. Obtain samples from Autobarn.
2. Send to my good friend the LED manufacturer in Taiwan.
3. Purchase eleventy billion led's
4. ....?
5. Profit!

these are convex the ones i used were concave
Toobs
30-07-2005, 03:40 PM
Looking at the design of your illumination I doubt it would really matter if you used convex or concave... the reason the older dashes don't light up so well is because the lights point directly onto the rear of the dials not into a "piece of plastic what glows" <--- Insert technical name here

The Witzl's Technical Name = Light Manipluators, or Illuminative perspex.
Perspex or other predominantly clear plastic which harness a high total internal reflection angle to carry light from a light source to a specific location for the purposes of controlled illumination.
Why are the old instrument clusters so dodgy?? As Toobs said, they use the globe and a light box behind the dial to hopefully throw some illumination onto the dials.

They wanted $21.99 a pair at Autobarn.... I like the idea and while I've got the dash out of the Corolla i was going to swap them over to red But not for over $60..
Regardless Puzzleman nice find.... They come in 3 and 7 colour varients as well.

Why didn't you figure out a way to get the Toyota symbol on your "povo pack" dash to light up while you were at it.
At least that part of the dash would've been useful then :p
I think you need a tacho, dude.
For the others reading this, if the dash doesn't use these wedge globes where you can get a replacement unit that already has a resistor in it, what's the best way to get LED's in there?
Use normal LED's in the original socket & solder a resistor in line on the wire to the cluster?
And if so, how do you determine the reisistance required? Is a potentiometer a possiblility?
Can you still dim the dash lights using the factory dimmer switch with LED's installed?
Isn't it funny how this would've been classed as RICE a couple of years ago... :rolleyes:

i can still dim them u best ask Karl as i would not no the size k~ resistor just a big one and you can run all the LEDS with one big k~ resistor (thats what i did with my speco tacho)

The Witzl
01-09-2005, 06:32 PM
you cannot dim LED's PROPERLY by reducing the voltage driving them. They will dim possibly ~5-10%, and then they'll just shut down. To properly dim an LED you have to vary the current to the LED whilst maintiaining a voltage just a little higher than the forward bias voltage (usually the rated as "typical operating voltage").
To do this you need a simple transistor circuit using a very common 30c transistor and suitable resistors and a trimpot to vary current. I have done it before, but it's buried in the "celica box" somewhere....
in most cases, running your typical 3.0-4.0V operating voltage LED at around 20-50mA from your car you should use approx 570 ohm resistor.
I'll be working on this more when i get stuck back into the real car.....

The lights in my dash have been shitting me since I've had the car. They are incredibly dim even when turned to the brightest setting and my old eyes can't see the gauges at night.
Do the LEDs come in plain old white light? Me being really smart and all, I'm guessing the one in the middle of the picture you put up is a white one Craig?

what i have is these nice new led strip lights... they use surface mounted LEDs on a nice flat strip which have a nice BRIGHT dispersed light, and run off 12Vdc.
basically the idea is that you put this inside the rear "light box" plastic casing on the back... and hook em up.... and BAM - shitloads more light than the bodgy 3 wedge lamps used from factory!

The connectors are on the back of them and they come with a little bracket with double sided tape on them for mounting.
They are made for the computer case mod types but would probably work pretty well in the instrument cluster of older (pre pentroof combustion chamber) vehicles.

I'd be thinking most 1980-1990 inst clusters would have been the same, I'll check my ADM and JDM Ke70 ones and post result here. I just bought 10 of the bulbs off the guy, will probably report quality and stuff here too.
I suppose it can be considered rice, but when you really think about it, the instrument clusters are already lit up a certain colour, where's the rice in just simply changing the colour?

OK, I recieved the leds within a day or two (Amazing postage speed!! Especially since they came from HK), installed them yesterday and they work great. Slightly dimmer than stock globes, but still well bright enough to view your speed and revs. I would recommend going for the wide angle ones for anyone willing to shell out a bit more though, as I suspect these would be much brighter.
But for $10+post this mod is definately worth it for someone who is sick of stock greeny-yellow. I ended up using 7 bulbs, including the 2 for my indicator dash lights. Didnt replace the warning lights, as they are coloured by the sheet of red plastic that has the writing on them, and it would come out... purple... if i put blue globes in ahhah.
Will take photos once I get my car back from the mechanic.

Does the AE86 have two sizes of bulbs in the dash (5mm & 9mm) like tha xA6x Celicas/Supras do?
If so, I've only seen suitable 5mm leds sold - what did you do about the 9mm ones?
Wiggles
30-11-2005, 05:44 PM
The blue ones i used in the photo above were the 9mm 168/194 type. I needed 4.
Here's a link to the ones i bought on ebay:
http://cgi.ebay.com.au/2pcs-T10-168-194-4-LED-Spark-Blue-Wedge-Bulb_W0QQcmdZViewItemQQcategoryZ102560QQitemZ45920 79814QQrdZ1
(I had no hassles buying from this guy but theres plenty of other people selling these things, so you don't have to use him.)
The AE86 dash uses 4 9mm bulbs for the main lighting.
9mm's are used fot the blinkers, high beams ect, but these shine through a coloured plastic lens, so no point changing them.
5mm lights are used for the idiot lights, these also shine through a red or orange filter.
You might have to clean up the contacts on the bulb holder and circuit board, i found that mine were pretty dirty and wouldn't run the center bulb until i shined up the contacts.

OK had a day off so thought i would pull my dash apart agen...
because i got a new tacho and it looked

and took some pic ..
the is the speedo cable some people were asking about..
http://img205.imageshack.us/img205/5000/dscf00065mt.jpg
the brassy looking thing is what you have to undo..
now went looking in my garage and pulled out a white pack i had from awhile ago
there was only 2 so went looking in my bag of trick and fond a convex one
so i got some 80 grit sand paper and ruffed it up (so the light would distribute better)
http://img220.imageshack.us/img220/2360/dscf00102ds.jpg
then put it all back 1 point i will make is when you put the LEDS in BEFORE you put all the dash back together make shore the LEDS work if there not working all you have to do is turn them around.
all finished and only took about 1/2 hr

As stated previously puzzleman, the early dashes dont have the perspex light diffuzer, so this becomes a little sadder for anyone with an early dash. One solution ive found to work decently in early dashes is to pull the guages completely apart, and then clean up the box behind them and spray with chrome paint. Go light coats for the best effect, not a perfect finish, but it does reflect the light around your instrument a lot, and works wonders for the lighting.
Cheers, Owen

ae86drift - As xolent said, just need to pull the dash cluster out, pull the old bulbs out ( being careful not to break the glass) and shove the new ones in.
As i said before, the only thing to look out for is dirty contacts on the plastic holders and the back of the cluster.
I recomend you turn the lights on to test that all the LED's light up before you screw everything back together - i had to pull it all apart when i figured out one LED didn't light up! :D
xolent - The guages wont be lit totally even, the spots just infront of the bulbs will always be brighter.
At night, you barly notice it unless you look for it.
In the arvo, with a bit of ambiant light you notice it a lot more.
[Edit: This is in the AE86, could be different in other models]
Bananaman - Those guages look fantastic.

Wiggles
20-12-2005, 09:57 PM
That would help, but the replacement bulbs i got are made of 4 tiny LEDs in a splade holder. Very fiddly to rough up for not much gain.
It comes down to the fact that LEDs just don't produce the same amount of light as incandecents.
The LEDs are more efficient (produce more light for a given amount of power than regular bulbs). But even 'wide angle' Super bright LEDs have a very narrow bright spot compared to incandesant bulbs that spew light in pretty much all directions.
Perhaps a luxeon star type LED with a reflector would produce better results ( more light with a wider distribution) but in a larger package and producing more heat. We will just have to wait for bigger and better LEDs.
Personally, i can live with the patchyness.

Do LED's give off much heat?
I have some small reptile enclosures that I'd like to illuminate, but putting a normal globe or fluro tube in isn't really appropriate for these particular encs. I need the illumination to not give off much heat. Can you get 240v LEDs or could I use a converter thing? In the open do they throw much light?
Cheers, Greg.
The Witzl
03-01-2006, 03:40 PM
Greg,
LED's typically give off fuck all heat, and a "normal" 5mm LED will draw a megre 20-30mA at around 2-4Vdc. Depending on how much light you want, there are most certainly options available to you in the world of LED technologies, or perhaps even CCFL.....
From 240Vac, you'd just use a little 12Vdc plugpack, and a 510ohm resistor for each LED to limit current. Alternatively those little "strip" LED's i recommended before will also work a treat, and work straight of 12Vdc and are a piece of piss to mount. I'll try to get something happening in the 28 to show you what it's like :)

I was just looking at the Jaycar webpage and liked the look of these. Not that there's an image of them but wondering how they'd go.

In my experience the concave ones from ebay are no where near bright enough for the dash... they illuminated the gauges a dull bluish white... going to try 9led and 5-led dispersed/refractor types.

Ok,
After seeing the concave ones in a Sprinter's dash, I can see that they do a good job of making it a nice white. It's not a very bright white, but good non the less...
I have purchased a number of 5-led and 9-led ones, the 9-led I purchased without thinking, they are very bright, but don't physically fit in the cluster! Will make good parkers/number plate globes...
The 5-led ones are a fair bit brighter than the concave leds, they do give you some spots that are a bit brighter than others, they seem to make the SX cluster (which has a blue backing behind the numbers etc on the dials...) appear white, quite a nice white. The Spark Blue, in my opinion, looks awesome in the SX cluster, they are very bright little buggers and again give some bright spots, but no where near as bad as say the single LED, or 2-led pointing straight.
So, in conclusion...
5-led Refractor type are quite passable.
Concave LEDs are passable, more suited to older clusters without the blue filtering on the back of the dials.
9-led are too big to fit.
9-led dome light is a nice item, though could be a little brighter...
Hope this helps someone purchasing led's on ebay... I know I have a fair few spares and a lighter wallet ;).

I did this on my supras climate control unit with DSE super whites, too patchy for my liking. Has the 'defuser plastic' but it doesn't seem to carry the LED light. Had to wire in resistors too, I've got a web site that you can use to work out what resistor you need. i can dig it up if anyones interested.
Any ideas on replacement LEDs that will defuse better? Just normal wire end ones would be nice as the climate control lights a wire backed wrapped around rubber braces. I was thinking of building a full circuit board strip of LED's but if theres a 'defused' one that'll work good then awesome!

I didn't know there was an easy alternative to this, so i made mine myself just recently using white LEDs from jaycar:

And the result:

Considerably better than the stock ke20 globes ;) Turned out pretty blue, but not bothered :)
Going to change my interior light over as well.
I've done something like that be4 for my old mans 4runner and my volvo, It worked a dream and we had 2 leds per skt so it lit up pretty bloody well as we were able to direct the lights. Appologies for lack of photos, i'll describe it as best i can. Also this wont work if the globe holder is bidirectional (the contact spreads the whole way across.)
Parts needed (can be bought from dick smiths or jaycar... i just happen to work at dick smiths)
1- Went and bought a prepunched PCB (which should cover all the globes, we had enough in one board to do both cars and have some left over)
2- (per bulb) 2 x LCD's in your choice of colour (cant remember if we used 3mm or 5mm led's thou)
3- (per bulb) One 250 ohm resistor (i used 1/4W metal film)
Ok, the PCB needs to be trimmed into sections 3 holes by 5 holes.
Now the LED's need to be secured at one end of the trimmed PCB, make sure you have +ve and -ve on same side. both legs should fit through one hole.
The +ve side needs to run all the way to the other end and double back at one of the half holes that you trimmed(the middle half hole doesnt get used).
The resistor needs to connect to the -ve legs of the led's and loop around the bottom like the +ve leg did.(the middle half hole doesnt get used)
You could solder it all up now.
Anyway once its soldered, notice how it fits wuite snugly in the wedge socket. Run some test power and it should light up. If it doesnt spread the light out properly you can aim the LEDs so it throws it out a bit better or lightly rub it with emery cloth (this normally dulls the LED something chronic.)
If the globe holder is bidirectional, you wont be able to loop the legs around the bottom, it'll just skip the circuit, you can trim the legs so they dont wrap around, but the reliability will be questionable unless its firmly secured.
