Strange green light at the air intake of the mac after ssd upgrade

I upgraded ssd 128gb to 512gb from my Macbook Pro Early 2015 (a1502), it was backed up via time machine

after installing the new ssd on mac, i restored the previous backup

Redefined PRAM and NVRAM

Redefined (SMC)

the system operates normally without errors but two strange things are happening on my mac

- whenever it starts, the loading bar appears with the club. before ssd upgrade only apple logo

- a strange green light flashes during mac startup and operation (it did not previously).

I didn't find any about these strange behaviors, can someone help me?

You’ll want to discuss this with the people that upgraded your Mac.

I suspect you’re simply seeing a green LED included with the new storage hardware.

The startup looks normal in both examples shown.
