This light switch is a key electrical component that controls the lighting system on the host tractor. It is an original AGCO part, meaning its internal contacts and housing geometry match the original assembly's specifications. A failing switch typically causes intermittent or non-functional lights, which reduces operator visibility and safety during low-light operation. The switch is installed in the dashboard or control panel and connects directly to the lighting circuit. On replacement, ensure the connector is fully seated and the switch locks into the panel opening.
