Help your back-up lamps come on when you select reverse with the Standard Ignition switch LS419, a back-up light switch that signals the reverse lamps whenever the vehicle is shifted into reverse. It is a direct-fit replacement for the 2011-2019 Ford Fiesta. See the Buyer's Guide tab for engine-specific application details.
A back-up light switch completes the back-up lamp circuit when reverse is selected and opens it again when you shift out of reverse. If a failed switch is the reason your back-up lights won't come on, stay on in other gears, or work only intermittently, the LS419 replaces it. Burned-out bulbs, blown fuses, and damaged wiring can cause the same symptoms, so diagnose the circuit before replacing the switch.
