RED POWER LIGHT: Router is going through a software (firmware) update.
POWER LIGHT OFF: Router is turned off. Or, router is in the process of being reset.
The USB light tells whether or not the USB light is operational and in use.
GREEN USB LIGHT: USB port is operational and is currently being used by some external device.
BLINKING GREEN USB LIGHT: USB port is operational and data transfer is currently occurring.
USB LIGHT OFF: USB port is currently not in use. If this indicator remains off even when a USB is connected to the port, then the USB port is non-operational and needs to be fixed.
The WPS light tells whether or not your Wi-Fi network is secured with a password.
By default, the WPS is disabled and your Wi-Fi network is open to all. To change this, head over to Admin Portal -> Wireless Settings -> WPS and turn it ON by setting a password.

The ethernet light indicator tells whether or not an ethernet port is currently active with a connected device.
GREEN ETHERNET LIGHT: Ethernet port is active and has a device connected.
BLINKING GREEN ETHERNET LIGHT: Ethernet port is active and is being currently used to transfer data with the connected device.
