Long story short there is a buzzer in the instrument cluster that has a few duties like buzzing noise for shifting gear, seat belts warning, and leaving lights on as far I know.
So, if you want to remove the shift light buzzer or do seatbelt warning delete you need to desolder and remove it which is very easy.
However, like me, if you want to add shift light you need to have more solid wires for led.
One of these pins is always positive and another negative as a switch.

Removing the instrument cluster and opening it is a 15 min job and only needs a Philips crew drive.
Also while you are at the back of gauges you could add some lighting gel to change the colors. I put some red below 2k rpm as a reminder
to stay away from dead gearing.
For the shift light, I used one of these leds, as they are cheap, bright, and have alu backplate so no thermal issue. Alo easy to bend and very thin to put over speedo.
I did measures the current of the led and had some R&D with those pins :d
It needs min adj and grinding on housing and totally invisible until they go off. The shots I took are very close and under-angled to show it.
It looks 100% OEM and no one can spot it.
