About This Product
This chrome-plated mechanical brake light switch is a faithful reproduction of the original pull-on action switches used on vintage Harleys. It is designed for 1939 to 1957 Big Twin models equipped with rear drum brakes. This switch is a direct replacement for OEM part numbers 72004-39 and 72003-34. Because it is a mechanical actuated system, it relies on the physical movement of the brake linkage to trigger the light. This part is sold as a kit and is essential for anyone restoring a Knucklehead or Panhead who wants to maintain the correct period-accurate look while ensuring their rear brake light functions reliably for modern road safety.
Manufacturer part number: 508775.
Fitment
39-57 Big Twin
