That's what makes turn signals work. Between the 1930s and early 1990s, they were a real simple and reliable mechanical unit that costs around $2.99 and lasted the life of the car. Today the engineers use an electronic module that can cost around $50.00. Because they have a lot of complicated circuitry inside, they fail much more often than the older part. The flashers now can be brand and model-specific, so you might consider finding a good used one at a salvage yard.
