This is a genuine OEM Mopar headlight switch for the 2019–2020 Ram 3500, Ram 4500, and Ram 5500 Chassis Cab trucks.

This switch is designed for vehicles built with OEM option code [X81] (standard North American instrument panel configuration) and option code [LBT] (without automatic or perimeter lighting). Supersedes previous part number 68401978AA.
