4AD Brake Light Switch

Post by Stephen »

Hi Everyone .. I have searched this forum and cannot see any reference to the brake light switch ??? I have almost completed the wiring on the 1952 4AD Roadster I am restoring, and there are two wires that are obviously for the brake light switch??? but as I had very little original wiring left I do not have a switch or know what it looks like ,.. can anyone help with a photo of the switch with wiring attached and where it goes ... there is a small plate under the floor with two holes in it, does the brake light switch mount on that ??? ?? .. Regards Stephen from Down Under

Stephen,

The switch is Lucas # 31281, fits Sunbeam 90 and Alpine 1949-56, Morgan Plus Four 1949, Austin A-90 Atlantic 1949, Hillman Husky 1957. Here are a couple of pictures and it is attached at that bracket with a spring hooked to the brake pedal that pulls the plunger on the switch.

Hi Brg .. Thank you for the answer and the photos .. I have a spring hanging down off the brake system, and now I know what it's for,.. I also have some friends in the car Club that I am a member of, that have several Austin's and many, many spares, so I will see if they can supply me with one, if not with the part number I may be able to source one somewhere .. many thanks for your help, and have a Happy & Safe NEW YEAR .. Regards Stephen

Hi Stephen,

The correct Lucas brake light switch is available as a reproduction if you are not able to find an original in a decent condition.

You can get one from many companies selling vintage electrical parts for classic cars like Holden

or Paul Beck
