It’s pretty common for a brake light bulb to blow out every now and again. If all the brake lights stop working, i.e nothing lights up when you press the brake pedal, then it’s most likely a problem with the wiring, relay or switches. If all your brake lights don’t come on then the switch may be faulty.

How is a brake light switch replaced?

It's a simple job on some cars and it can be a real pain in others. The mechanic will remove any floor mats or carpets that prevent access to the switchboard. The switch will be disconnected from any wiring and removed to be replaced with a new one and the operation will be tested before returning the car to the customer. The difficulty can come if the switchboard is hidden behind a whole bunch of stuff that will have to be disconnected and then reconnected - this can soak up some labor time.
