Detailed Product Overview

Standard Ignition SLS-255 is a brake light switch engineered for vehicles that rely on accurate stoplamp activation at the pedal assembly. The switch design uses durable housing materials and a spring-and-contact arrangement intended to limit arcing, while copper alloy conductors help maintain consistent current flow. This makes the SLS-255 a practical replacement for Ford F-150, Ford Expedition, Lincoln Navigator, and related applications where reliable brake lamp signaling is required.
