This switch controls the forward-facing work lights from the dashboard. It is a push-button or rocker-style component that completes the circuit to the lighting relay when actuated. The switch is mounted in the dashboard panel and is part of the operator's primary lighting controls. A failed switch will prevent the work lights from turning on, or may cause intermittent operation. The switch body matches the cutout dimensions of the original dashboard panel, so no adapter or panel modification is needed for installation.
