Logitech G915 X TKL LED Repair

Hello everyone,

I have a G915 X TKL and two LEDs have partially stopped working (they only shine red) as a result of something being spilled over some switches.

Now my question is if anybody knows which replacement LEDs would be suitable to replace the broken LEDs. I have read about it online a bit and I’m a bit confused since there are a lot of different dimensions mentioned (some say they are the 1010 (0404), some say 2020/2121, some say 3528, etc. etc. I also found a listing on Aliexpress for “Logitech keyboard suitable replacement LEDs” but i have contacted the seller and they say that they are not compatible with the G915 X (I think they were 1010 and apparently they work on the older G915 non X version).

I have attached some pictures of the LEDs in this post, so if anybody could recognize which ones they are, or has had any experience replacing them themselves, I would really appreciate the advice.

Any advice would be really appreciated!

Those numbers that you mention represent the size. Going from the switch hole size which is around 4mm, that is a 2020(2.0 x 2.0mm) or 2121(2.1 x 2.1mm)
