Check the Raspberry Pi’s Red and Green LED Lights. When a Raspberry Pi boots, one or more LEDs will activate. One is red, indicating power (PWR); the other is green, and indicates activity (ACT). (There is also a trio of green Raspberry Pi LED lights indicating the Ethernet status, if connected.)

What lights should be on Raspberry Pi?

Raspberry Pi LEDs

  • ACT – D5 [Green] – SD Card Access (via GPIO 16)
  • PWR – D6 [Red] – 3.3 V Power is present.
  • FDX – D7 [Green] – Full Duplex (LAN) connected (Model B)
  • LNK – D8 [Green] – Link/Activity (LAN) (Model B)
  • 100 – D9 [Yellow] – 10/100 Mbit (LAN) connected (Model B)

Why is there a red light on my Raspberry Pi?

A constant red light, the PWR led, indicates that your raspi is properly powered up. With a bad power supply it would flash below 4,63 V. So you do not have to worry about your power supply with 1 A output. It’s enough in this case.
