LED size / number

[hellothere]

I have a couple of Focus Key Pro keyboards and I want to change the three LEDs (yellow Alps switches) to something other than red. According to this thread, the measurements for green Alps are a bit less than 2mm x 4.9mm. The closest size LEDs I see on Amazon is 2mm x 5mm x 7 mm. Is 2x5x7 the correct measurement? Do you have the correct measurements? I don't have calipers to measure the LEDs on the Keypro, myself.
