I recently saw that my Raspberry Pi's red light (power light) flashes every few seconds. Is this normal? If not what could be the cause?

I am using a raspberry pi 2 connected to a monitor, keyboard and mouse.

Sounds like you may have a power issue :

Red power LED is blinking

A blinking red power LED indicates problems with the power supply. On model A and B, it is hard-wired to the 3.3V power supply rail. If it is blinking, as one user has reported[1] it means the 5V power supply is dropping out. Use a different power supply.

On model B+ (and presumably also the A+), the circuit has been improved to give a much more reliable warning of poor power quality. The red power LED is wired to an APX803 supervisor[2] which kicks in when the 5V power supply drops below 4.63V[3]. If it does, the LED will blink. Check your connections, cable, and power supply.

What is the specification of your power supply?

Used a higher Amp USB socket, and works fine now.
