Most flashers are located under the dashboard on the driver's side. When working properly, a flasher is easy to locate because it makes a ticking sound. When it is not functioning, a service manual may be needed to help locate it. Lighting company catalogs generally have pages listing the location of flashers.

- A flasher features two or three prongs that plug into a socket.
- Just pull the flasher out of the socket and replace it with a new one.
