ANYONE DONE a Logitech G27 shift light mod

[sean05]

anyone? i was thinking of doing this adding additional LED. on top brighter LED that is. but not sure if anyone has done it before.

I was considering doing this to mine. The RPM display you see on top of the wheel, aren't really LED's. They are mounted directly to the curcuit board and are very tiny. The light then travels up a "periscope" and that's what you see on top. The problem I had was soldering/tapping into the circuit board without damaging my wheel ( I don't have the skills needed)

Its possible but you need to know your stuff about soldering and wiring to do it.
Ive wanted to do this and put some lights into the top of the wheel so its more visible.

I would really really like to know how to do this as well...i already have a shift light ready but don't know where to start. So please post a DIY if anyone decides to do it. Thank you in advance!

I will try to find one as ive wanted to do this ever since i got a g27. I hate looking down to see my shifter lights and i want to place some on the top of my wheel rim.

EDIT: its pretty hard to find instructions on how to do it. Going to keep searching though

Ok i will do this MOD. Good thing im good at soldering... This will take a while i will be using an actual mini shift light from my old S2K.... Hoping someone can chime in before i do this mod....

I was worried about this as well myself, but i am replacing it with a MOMO steering wheels anyways with CHILICOKE adaptor. so this should be an interesting mod... this is what i will be putting...

PLAN: I will be removing the circuit board and relocating inside the main steering case. if that doesnt work i will be putting it under my playseat. Then i will be putting the shift light right behind the steering wheel.

SHIFT LIGHT... WILL BE USING JUST THE LIGHT

Steering wheel MOMO 250 SUEDE

CHILICOKE ADAPTOR

If you can solder into the power circuit for the Led's , you can make your shift light or RPM indicator with any LED bulbs. Which would be a lot cheaper.
I wanted to make a similar rev indcator with larger brighter LED's in the same place as the existing one but not sure if there would be adaquate power for brighter LED's to work though.

it looks complicated. i wish i could just tap into a wire or something but it's not the case
i thought about putting a small magnifying glass over it to give it a boost, not sure if it'll work though and it might look ghetto

yea it does look like its complicated... i have seen the inside of the wheel and when removing the steering wheel im just hoping i can run a wire somewhere inside the wheel case.... also im hoping that i can take the shift light apart to solder the high LED lights... ill find out if this is possible.

magnifying glass isnt so bad but i just dont want it to look all tacky.. but good idea..

Ok update will be tonight... i will try to attach the light to see if it even works... not sure how much Voltage power coming out on the G27 shift light, ill find out tonight if its even enough power to power up the light.

not sure how much Voltage power coming out on the G27 shift light,

I'd imagine it's around 1.8V at 20mA going across the LED itself. Be aware that replacing an LED for another LED might not really do anything, it's hard to say for sure with no knowledge of the G27 but I imagine the LED has it's own current limiting resistor so the tracks the (presumably surface mounted) LED is on will only ever give you the amount of power they're already giving, so you wouldn't see any increase in light if you add an LED with a higher power rating.

The best thing you can do (in my opinion), if you want to do it properly, is replace the LED with an optoisolator or solid state relay and use it to control a separate circuit with your shift light on it. I wouldn't be able to show you exactly what I mean until Sunday as I'm away from home until then, but with a soldering iron, some stripboard, £5 worth of parts and some skill, you could have a much brighter shift light without damaging your G27 beyond removing the existing LED.

thanks for the heads up ... ill try it anyways and if it doesnt work.. oh well... im going to do other mods... HAHA... HANDBRAKE AND STEERING WHEEL.. sucks i really do hope it does work... LOL...
