The simple answer is, find out what's wrong then repair or replace any component that isn't working properly.
But it isn't that simple. Finding the faulty component is the hard part.
You need electrical diagnostic skills to track down a faulty turn signal, and you need to understand switching circuitry. There are a couple ways that auto manufacturers implemented turn signals and brake lights. You need to figure out which circuitry yours uses, learn what to expect when different components fail, then figure out a way to diagnose the problem that doesn't end up destroying any good components.
The hardest part of automobile repair is diagnosing the problem. Turning a few bolts and putting in a new component is relatively easy.
