See the Buyer's Guide tab for the full list of applications.
A flasher interrupts current to the hazard and turn signal lamps so they blink. It may need replacing if your hazard lamps or turn signals won't flash, stay lit steadily, or blink erratically. Burned-out bulbs, fuses, switches and wiring can cause similar symptoms, so check those before replacing the flasher.
