This hydraulic stop or brake light switch is the right one for just about every British car made in the 1960s and 1970s, including MGB, Mini, Triumph TR4, TR6, Spitfire, and Healey. It is also the correct switch for Volvo 122 Amazon, possibly Alfa-Romeos, and other cars. It has a 1/8" pipe thread and is pretty close to a universal switch. It is brand new in the original Lucas box.
We also sell an uprated switch; see Related Products below.
