First and for most, I would like to clarify a few questions I have been asked. The gauge cluster and HVAC controls you will see in the following pictures or the first pictures are not aftermarket, not reverse-glo, not special edition or anything else. My gauge cluster and HVAC controls are the ones that were installed in my car from the factory.

Q. Now you might be asking, why do my gauges and controls look "bluer" or "brighter" than all of the other "stock" gauge clusters and HVAC controls?
A. I swapped out the stock "incandescent" bulbs in my cluster and controls with super bright "LED's."

Q. So what's the difference in the incandescent bulbs and LED bulbs and why does it make it appear blue?
A. Behind our clusters and HVAC controls lies a blue film (the film behind the number and dial cut outs are blue). An incandescent bulb emits a yellowish light (like most household bulbs that are incandescent). When you mix this yellowish light with a blue film, you get a green hue showing through the numbers of our clusters and dials of our controls. NOW, when you take the stock incandescent bulbs out and swap in their places the super bright, pure white LED's and mix it with the stock blue film, you get a BLUE hue. So white and blue = blue. Hopefully you get what im saying. That is why my gauge numbers and HVAC controls are now BLUE and not the stock green.

What you will need

7 Super Bright White LED's - Socket 194/168 (sockets are the same, just different numbers)
I bought my LED's from here (mine are the WLED-x5 Wedge Based Bulbs)

For 1999 - 2004 Mustangs you need 74-xHP3. The "x" denotes a color code so for example if you order green it'll say 74-GHP3.

A T-15 Torx Screwdriver

A 2 mm (i believe that's what it was) allen/hex wrench. YOU ONLY NEED THIS IF YOU HAVE AN AFTERMARKET HEADLIGHT KNOB!



OK, so lets get started!

Step 1

Start with your untouched gauge cluster.

Remove the two T-15 Torx head screws.

Step 2

"You need to pull a retainer clip outwards (away from the shaft) and then pull this knob off gently." - MustangWorld.com

Aftermarket Headlight Knob

Remove the 2 mm Allen/Hex screw in the side of your Headlight Knob Switch

Step 3

Once you have the knob taken care of, carefully remove the gauge clusters bezel (clusters surrounding piece). It will be stubborn more than likely but it should come out, just try not to break it! After the bezel is out, unscrew the four surrounding bolts to remove the cluster itself. They are again T-15 Torx headed bolts.

Step 4

Tilt the cluster by bringing the bottom out first. (like you would be putting the gauge faces pointing upwards)

Step 4.1

Remove the black connector that is connected into the back of the cluster. Carefully pull it straight back and out.

Step 4.2

Notice the white connector on the opposite end of the gauge cluster. Just like the black connector, remove the white connector the same way. Carefully pull straight back and out.

Step 5

Once the two connectors are unplugged from the back of the cluster, carefully pull the cluster out. (It helps if you have the wheel tilted as low as it can go). From there, flip the cluster over and notice the 5 black TWIST style sockets. Untwisting the black sockets to the left will unlock them and allow you to pull them straight out.

Step 6

Notice MY already installed LED.

To replace the bulbs with your new LED's, simply pull the stock bulb out and replace with the LED. Put all the sockets back into the holes and get ready to reinstall the cluster!

So CONGRATS, we are halfway done with the swap! See, its not so bad right!?


Step 7

Start by re-inserting the white connector the the back of the gauge cluster. Do not force it in, it will go in if you have it aligned right. It will require a bit of pressure but not 100% strength lol.

Step 7.1

Then go to the opposite side of the cluster and reinsert the black connector. Rules are the same as the white connector.

Step 7.2
Reinsert the Cluster with the gauge faces pointing upwards again and slide the bottom up and back to insert the cluster in its original position.

Step 7.3
ATTENTION! I would now suggest that you reconnect the negative battery cable to ensure your newly installed LED's are all working! Once you verify they are all on and in working condition, go back and DISCONNECT your negative battery cable.

Step 8

Screw in the 4 T-15 Torx headed bolts to hold the cluster in place (be careful not to drop the bolts behind the cluster, you may not get them back!)

Step 9

ATTENTION! Don't forget about the HEADLIGHT KNOB! I've done this and reinstalled everything and its annoying to think your done and then notice your missing a headlight knob! Go ahead and pull out the headlight knobs shaft to the ON position and THEN install the gauge clusters bezel.

Step 10

Reinstall your Headlight Knob with your 2 mm Allen/Hex wrench or simply push your stock knob back on (i remember having to adjust the retaining clip inside the knob when I had mine so you may have to play with it)

Step 11

Reinstall the two T-15 Torx headed bolts into the clusters bezel and vwalah! or walah! or.... you get the point.

So, we have no completed the gauge cluster LED swap! If you are continuing on and doing the HVAC control LED swap, now is a great time to have a coke or a beer ;)


Step 1

Here we start with a stock HVAC control head unit. If you have a DVD player, make sure you fold the face down before unplugging the negative battery cable.

Step 2

Here I undid my shifter knob so I can remove the shifters bezel and boot.

Step 2.1

Once the shifter bezel and boot is taken off of the main console, unplug the cigarette lighter.

Step 3

Continuing, unscrew the two T-15 Torx headed screws securing the bezel.

Step 4

After taking out your stereo's head unit, take your extensions as well as your 8mm (i believe that's what I used) socket and socket wrench.

Unscrew the 8mm headed bolt that secure the bezel in place inside of the dash. (It is directly behind the stereo head unit. Follow the long black plastic piece)

Step 5

YAY! Our bezel can now come off after a few pulls around the perimeter of the bezel! Like the gauge cluster bezel, be careful not to break it! The bezel will be stubborn but should come out with a bit of strength!

Step 6

Here is the long black piece attached to the bezel and the hole that the 8mm screw goes in.

Step 7

After the bezel is removed and carefully set down to avoid scratches, take your T-15 Torx screw driver and unscrew the four bolts holding the HVAC controls in place.

Step 7.1

Once the four bolts are removed, carefully pull out the HVAC control unit and look for the 2 black TWIST style sockets. (These are exactly the same as the gauge cluster sockets)

Step 8
Twist out the sockets, replace the bulbs, and reinstall.
ATTENTION! I would suggest replugging up the negative battery cable and making sure the LED's work like before. Once you verify they are working, go ahead and unplug the negative battery cable again. After doing that, reinstall EVERYTHING in REVERSE order! Reconnect your negative battery cable, pull the headlight knob and again, VWALAH! You should now be greeted with a nice blue gauge cluster and HVAC controls!

That's it! Not to long of a job but it can be aggravating. However, the results definitely speak for themselves! Hope my HOW TO was easy to follow and you got the output you desired

After shots!

Change the position of the bulb by taking out and rotating the bulb, put back in and it should work. It depends on the position of the bulb, I replaced all of my gauge lights and half of them didn't work, and I realized that if I rotate the ones that weren't working they worked after plugging it back in. Hope this helps someone else in the more present day

Just did this on my 98 Cobra with relative ease. Already knew how to take out the gauge cluster due to having to replace the odometer gear, so the tricky part was the HVAC. I actually had to use a 7mm socket, but beyond that the walkthrough was good. Also swapped out the license plate bulbs with led's, they use the same size all around on the 94-98's.

Just an FYI, dont think it was mentioned in the guide but here:

99 to mid 01 mustangs have a blue tint on your factory gauge overlay.
Mid 01 to 04 have a green tint on your factory gauge overlay.

this means if u have a 99-01, all you need to do is replace the bulbs with Cool White LED bulbs, if u have a mid 01-04 u need to sand off all the green tint within the cluster and add blue tint

for 94-98, i am not sure

I was bored and changed out the stock bulbs for LED bulbs in my 2003 GT and noticed with the HVAC controls I pulled the knobs off, removed the plastic lenses and sanded the green tint away to see if it made a difference, Hands down it made a huge improvement. It lights up much brighter. I plan to remove the HVAC face and sand off the green tint so it gives it a more crisp look then a dull blue or green color.

I have even had this happen before w/ LED's & didn't even think about it?? The width of the bulb & the hole size do not match.......So I had to notch out 1 side of each hole to get the bulbs in.

Subject: Actually, he's wrong...

Some stuff he's wrong about, and some stuff he doesn't show.
First of all, the tint behind the numbers are green.
Thats why it looks green when the lights are on.
In order to get rid of the green, you must take the front plastic protective bubble off of the cluster, this will expose the needles and the face-plate.
Here's the tricky part.
You have to take the needles off.
If i were you, I would let your car run for a while, get warmed up, and sit at an idle. Do this in a controlled environment like a garage. Take a picture of where the needles sit at, down to the very tick mark.
Keep this picture.
Now, using a razor, or very pointy, flathead screw driver, begin peeling the black face-plate up.
Once this is done, take some medium grit sandpaper and sand all the green off behind any numbers, letters, lines, etc.
Put the face-plate back onto the cluster, and reconnect any wires.
Turn the car on, let it idle, and warm up. Now reattach the needles in the same location as in the picture, reassemble the protective bubble, then just insert whatever color LED lights you want, and enjoy!

I was pretty excited to try this on my fox body. i figured since the sn95 has a blue film that gives off a green hue from the standard bulb, that it was probably the same for my fox because the stock gauges light up green.

Well, it's that time of the year agin... changing the bulbs behind the cluster again. Had to order another batch of 7 as the HVAC is long dead and it's still too cold to go aout and spend the time on that one. Dash takes all of 10 minutes to do. Love the look but it's getting annoying. Still not ready to go back to regular bulbs though.

I've seen other posts on different forums about the same problem though and I verified that it is not all the same seller. Seems to be a Mustang issue. Luck of the draw I guess. But like I said, the look behind the dash cannot be beat. I won't go bak to regular bulbs. Instrument console takes 10 minutes to do. Center console is a tad longer because of that bolt at the back but the mod is so worth it.

Subject: 2001 cobra

I'd like to do this but, was wondering what size I need for my 01 cobra and should I install a reflector behind to reflect the light? Also, if my car has a green film couldn't I just buy yellow lights then I would have a dark blue? Or get white lights and get different films to adjust to the appropriate color I'm looking for? I just want a dark blue color light and want it to be much brighter as well.

Subject: Important:: Color of Bulbs and Color of Lenses

You might want to know that if a lense color is blue you should use a blue bulb. Same goes for brake lights. Use red bulbs for red lenses. A colored lense is attempting to filter out everything but that color. So if you really want BLUE, use blue bulbs even though the lense tint is blue. I know it sounds counterintuitive...

I have a 2002 v6 mustang, will the red 74-redHP3 work with the green backing flim on the guage? Or will it make some sort of off yellow or orange color? GREAT HOW TO BTW!!!!!!!!

May 10, 2010 - 01:38 PM

ok, confirmed. i have 03 gt and bought the super bright white LEDs size 74. they fit BUT the glow was still green. so those of us with 03's at least have to file the green film out then purchase blue leds.

hope this helped

i have an 01 v6 and im wondering what bulb sizes i will need. im thinking its 5 of the x5hp3 and 2 of the 74... am i correct? also i want my dash to be blue... what color of film do i have?

April 20, 2010 - 07:35 PM

Subject: 99-04 cars

I've got a 99 GT and purchased 7 of the 74-CWHP3 LEDs. Just as a heads up they worked just fine for the Gauges but they are TOO SMALL for the HVAC bulb holders. The LEDs that you use for the HVAC are the same as the ones used in the install guide above (WLED-x5), this was the case in my 99 so I assume this applies to all 99-04 cars. Hope this helps!

Subject: 99 GT

I did this mod to my 99 GT and the 74 bulbs worked for the main lights, but I want to swap out the O/D light, the wheel spin light, the turn signal lights, and if possible the color of the odometer because they are still green. and the main 6 gauges are blue. For the TC button, fog lights, and rear defrost, i busted open the switches and removed the blue shield on the bulbs so that they are all orangish white and not green, but I just need the bulb size for the smaller indicator lights in the 99 and ups gauge. Does anyone know what I am talking about? The lights the light up the parking brake, theft, abs, O/D wheelspin, engine coolant, service engine, etc. What size bulbs are those? If someone can answer this, you are the man!

Did you try switching the direction you placed the LEDs into your cluster? If you don't allign the positive/negative terminal of the bulb with the corresponding positive/negative terminal of your cluster then it won't illuminate.

I tell you this was a great write up. I have order my LED's and I hope to see them turn out as great as yours. I have a 98 Cobra and man it just sucks trying to see the gauge at night. I can not wait. I will post some pix if I can. thank you so much for your time and effort. Also, is the HVAC worth the work. It straight look like some time maybe a couple of beers and I will be good.

Nice write up, but I read somewhere that the 00-04 Mustang gauge film is green not blue and that you would have to dremel the green film off and replace it with blue film in order to get blue lights. Is this true? I would like to do this, but don't want to go into that much work.

Subject: 99-04 MUSTANG BULB SIZE

Hey guys wassup. I saw that some guys were commenting on what size bulb they need for a 99 Cobra, 00 GT, and 04 GT. Well Im here to tell you. I have a 2003 Mustang GT and I saw that you guys said the bulb that the man above was posting for his 98 cobra wasnt working in the 99-04 mustangs. The reason why is because our (99-04) clusters are electrically controlled theirs (94-98) are mechanically controlled.

Anyways the bulb size for a 99-04 mustang is a 74-GHP3 you can get it from the above website that he posted. Your bulb size may not have a "G" in it mine has it because I ordered bulbs that were green so for example if you order blue bulbs for your car it'll say 74-BHP3.

Super write up. Ordered the bulbs of e-bay and going to tackle this as soon as they arrive.
Hopefully this works exactly the same on my '96.
Just wonder about the factory Mach 460 sound system and a way to change the bulbs on this to match.
If anybody knows, please give info.

hey i thought you could change the Mach 460 lights, but you cant, so i just went ahead and bought a Kenwood CD player with the blue lights so it would match, i took the 460 radio and CD player apart and there is no way to change the lights they are actually on the main circuit board..hope this helps

July 15, 2009 - 08:51 PM

Great write up but i am having a bit of a problem, i purchased the same bulbs you have and ran into a problem, the bulbs in mine are smaller, i have a 2000 GT would the Cobra's be different? do you think the 74-xHP Wedge Base LED Bulbs will work instead of the ones you have? thanks

They work on my 2002 GT. I ordered the 74-xHP in blue, and it came out almost an aqua color, but definitely an improvement if you're looking for blue. I don't know if using white would've made a difference, but when the result after blue lights is aqua, it's safe to assume the gauges in our mustangs have a somewhat greenish tint. Mine don't light as bright as Mike's but definitely do the job.

Also forgot to mention, the Wedges he recommends work on the A/C knobs, and my dimmer worked until i changed my gauges, but after that swap, the dimmer stopped working

First off great write up. I purchased the WLED-B5 (194) wedge base bulbs. When I removed my instrument cluster gauge I realized the bulbs seemed bigger and would not wedge into the socket base. Do you know what bulbs I need? Thank you in advance.
