Check wiring to the rear of the cluster. If it is good, have the cluster itself tested.

I'm sorry if this is a stupid question but how do I access the wiring? And if it is not the wiring then do I need to take to a mechanic to have it checked?

The wiring is behind the cluster. You need to craw under to see it. As far as the cluster, yes, it will need a series of tests run.

Yes, chances are the lights are coming on due to a faulty brake sensor.
