Introduction: Change Led Color on the Logitech G502

If you own the G502 from Logitech you know how good this mouse is. However it lacks the possibility to change led colors so that it matches your other stuff like keyboard,case lighting or gamepad lighting. If you are like me and want things to match then this is how to do it.

Step 1: What Do You Need



• Pry tool or a guitar pick
• Philips screwdriver
• Soldering iron
• Solder wick
• soldering tin lead wire
• 10x or more (As you will loose some while soldering) smd leds size:0603 minimal voltage 1,5V Max voltage 3,5(Any color you like)
• Hotline games mouse skates for G502
• Gloss black spray paint
• And some experience with soldering/desoldering

Step 2: Mouse Disassembly

Remove the mouse skates that are labelled in the picture with the red circles. Underneath them there are four screw that need to be removed. Once you've done that you start to carefully pry the back of the mouse open like you see in the picture. Use the pry tools so you don't damage the mouse. Work your way to the front en try to unclick the the pins that are showed in the picture.

Step 3: Changing the Leds

Once you've opened the mouse you will see the two smd leds where the red circle is in the image. First you need to desolder them to do this you need to add soldering wire so that both side are fluid at the same time. Then you can remove the smd leds by using tweezers or something else to push them. There is a trick to make it easier but you need a piece of copper wire. When the leds are removed you can start to remove the remnants of the tin with the solder wick. As you see on the image there is a dot on the pcb wich shows the - wich is the cathode of the led. This dot and the green line on the led must be on the same side. the two leds need to be placed next to each other. The original leds are two in one but the ones we use are seperated so you need to solder one by one. If you like you can also change the blue indication leds that show the dpi setting. These are marked in the image with the red circles.

Step 4: Painting the Blue Part

You can paint the blue part black if you like so that it looks better. To do this all you need is some gloss black spraypaint some tape to cover the the parts you dont want to paint and some solvent to clean the part before painting it. I used white spirit

Step 5: Placing the New Mouse Skates

When your mouse is ready and closed then you can put the new mouse skates on. It's very difficult to remove the original skates without damaging them. So I recommend you to buy the hotline games mouse skates off ebay or amazon so that your mouse looks like new again. If you have any questions feel free to ask in the comments area I will reply as soon as I can.

I want to just change it to a pure blue to match my Deepcool Tessaract case, is there a chance I could achieve this through software?

I believe the new mouse from logitech is rgb.

Will this also work on a Logitech g402? I really want a red led.

I suppose it does.. You only have to find out where the led actually is..

I found this high res image, but no idea where it's located..

How hard can finding the LED be? Cant i just plug in the mouse with the cover taken off?

Yep! Just remove the lid, plug it in and remove what lights up :) :)

I was going to get the g402 in about a week, but the g502 is on sale right now, so ill just get the 502.

Does it have to be 2.3v max? I want green but the voltage goes 3.2v – 3.8v.

It doesn't have to be 2.3v max but thats the original max voltage of the mouse. If you take a higher max voltage it may be that it doesn't light as bright as you would like. But it will light up

yeah that's my problem! the instructions says "Minimal voltage must be 2,3V".

but most LEDs I find are actually 1.8-2.2 V max.

Can you help me choose?

1,8-2,2 V leds are perfect I've made some adjustments to the tutorial because a lot of people get confused by the smd led part. 2.3v is the max output voltage the mouse gives minimal voltage is not important. The 0.1V difference of the leds you found is not a problem. for the size of the led 0603 is a standard so if you look by this it should be good. I've put a picture of the measurements in millimeters so you can compare. Hope this helps

YOU FREAKIN ROCK!!!! THANK YOU!

Congrats on the guide, you got me convinced to do the same!
Now I have a problem with choosing the LEDs.

Can i pick some models like this:

http://www.mercateo.cz/p/live_cz~s.20*2806-HSMS(2d...

I'm looking at electronic shops and some have different voltage, some have different dimensions etc.

I don't want to screw up :) please help!

hey, im thinking about buying a g502 is it a good mouse? and how big is it? and awesome instructable man im going to do thath if i buy one

It is one of my daily drivers, the other being the g700s. I swear by these mice. Some people have an issue with the scroll wheel but I personally love it. I've also seen people add plastidip rubber paint to give it a more grippy feel.

I just bought one, the only thing i dislike about it was the metal scroll wheel was too slick. I just removed it, masked the center and coated it with plastidip. Now I just love it.

Amazing guide.

I was going to try and just paint the blue part (thumb rest). Does it come off and what type of spray paint did you use? Is the paint holding? Thanks.

were you able to remove the plastic piece that covers the dpi indicator leds? or did you end up partially melting through it to remove the old leds?

also, I'm only counting 5 leds used. Believe me, I know that someone that hasn't done smd soldering before is going to need extra, but are all 10 used, or are you figuring in for... for...*achoo*... and there goes 4 leds that I'll never see again. Haha.
